2004-05-10[PATCH] cpqarray update for 2.6Andrew Morton-1/+1
From: <mikem@beardog.cca.cpqcorp.net> This patch fixes 2 minor issues that break our Array Configuration utility. my_io was changed to a pointer so the & had to removed when using it with copy_to_user(). Sometime in 2.5 SG_MAX got changed to 31. Maybe to copy cciss? Now I'm changing it back to 32 so our app can work.
2004-03-30[PATCH] double semicolon cleanupAlexander Stohr-1/+1
This cleans up a larger amount of superfluos ";;" statements in current Linux kernel sources by converting them to the regular single ";" statments. It seems to be a common problem that at the end of a line the semicolon key is producing an echo.

From: Luiz Capitulino <lcapitulino@prefeitura.sp.gov.br> Fix cpqarray.c warnings: `proc_array' and `ida_proc_get_info' defined but not used ida_proc_get_info() is only called when CONFIG_PROC_FS=y.
2003-08-30[PATCH] dev_t handling cleanups (10/12)Alexander Viro-1/+1
new helper - iminor(inode); defined as minor(inode->i_rdev); lots and lots of places in drivers had been switched to it.
2003-08-06[PATCH] Proper block queue reference countingJens Axboe-10/+15
To be able to properly be able to keep references to block queues, we make blk_init_queue() return the queue that it initialized, and let it be independently allocated and then cleaned up on the last reference. I have grepped high and low, and there really shouldn't be any broken uses of blk_init_queue() in the kernel drivers left. The added bonus being blk_init_queue() error checking is explicit now, most of the drivers were broken in this regard (even IDE/SCSI). No drivers have embedded request queue structures. Drivers that don't use blk_init_queue() but blk_queue_make_request(), should allocate the queue with blk_alloc_queue(gfp_mask). I've converted all of them to do that, too. They can call blk_cleanup_queue() now too, using the define blk_put_queue() is probably cleaner though.
2003-07-16[PATCH] remove all #include <blk.h>'sAdrian Bunk-1/+0
This causes blk.h to print a warning and removes all uses of blk.h. I've tested the compilation in 2.6.0-test1 with a .config that tries to compile as many drivers as possible.
2003-06-10[PATCH] cpqarray.c: fix stack usageAndrew Morton-7/+19
From: Jorn Engel <joern@wohnheim.fh-wedel.de> Reduce stack usage in the cpqarray ioctl byt several hundred bytes.
2003-05-24[PATCH] cpqarray fixesAlexander Viro-52/+58
This restores the special-case behaviour of open() on the minor 0; cpqarray allows to open that guy for ioctls even if nothing is configured. That got broken when gendisk patches went in. Patch restores the old behaviour by keeping gendisk for the first disk on controller always registered; instead of unregistering it we set size to 0.
2003-04-20[PATCH] irqs: drivers/blockAndrew Morton-3/+4
update drivers/block for new IRQ API.
2003-04-17[PATCH] devfs: cleanup partition handling interactionChristoph Hellwig-5/+3
Always pass around the pathnames for the devfs entries / directories instead of the devfs_handle_ts. Cleanes up the code massivly.
2003-04-06[PATCH] kill blk_queue_empty()Jens Axboe-2/+2
This finally kills of blk_queue_empty(). This is similar to the patch I recently sent to fix the SCSI logic as well. A lot of drivers are doing this in our core, mainly because that is the way they always did it: start_queue: if (blk_queue_empty(q)) return; rq = elv_next_request(q); if (!rq) return; Patch simply removes the blk_queue_empty() check, and adds a check for !rq return from elv_next_request() if the driver didn't already do that. Additionally, the AS io scheduler can return NULL from elv_next_request() if it thinks this is best. This way we are also prepared for that to work well. Patch was done by Nick Piggin.
2003-03-23[PATCH] devfs_mk_dir simplificationChristoph Hellwig-3/+2
All arguments except the name are unused - remove them and make the name printf-like to avoid a few snprintf in the surrounding code. (also fixes compilation to due a superflous endif in dvb core)
2003-03-08[PATCH] register_blkdev cleanupsAndrew Morton-4/+2
Patch from Andries.Brouwer@cwi.nl The following patch does the following: - static const char *blkdevs[MAX_BLKDEV]; disappears - get_blkdev_list, (un)register_blkdev, __bdevname are moved from block_dev.c to genhd.c - the third "fops" parameter of register_blkdev was unused; now removed everywhere - zillions of places had printk("cannot get major") upon error return from register_blkdev; removed all of these and inserted a single printk in register_blkdev. Of course the reason for the patch is that one fixed size array is eliminated.
2003-02-25[PATCH] replace its with it's where appropriate.Steven Cole-1/+1
This patch replaces its (possessive of it) with it's (it is) in the following cases where "it is" is meant. its a -> it's a its an -> it's an its not -> it's not except for the files arch/cris/boot/rescue/head.S arch/cris/kernel/kgdb.c where the substitution is "its not" -> "it is not" to avoid possible problems with single quotes in assembly comments.
2003-02-05[PATCH] Spelling fixesSteven Cole-1/+1
OK, here is the diff against 2.5.59-bk2, now up to 880 lines due to an additional misspelling which crept in the -bk2 snapshot. Fixes 'seperate' -> 'separate' and 'definate' -> 'definite'. Kernal codrs cna't spel.
2002-12-04[PATCH] get rid of MAJOR_NRChristoph Hellwig-18/+13
In <= 2.4 some of the mess in blk.h needed it defined, but that's long gone now.
2002-12-03[PATCH] cpqarray cleanupAlexander Viro-1/+1
switched to explicit devfs_remove()
2002-11-17[PATCH] devfs_remove() helperAlexander Viro-2/+2
All callers of devfs_find_and_unregister() pass 0 in 6th argument. All uses of that function either pass 0 in 3rd and 4th argument (in which case the 5th is ignored) or pass the existing pathname in the 2nd (in which case 3rd, 4th and 5th are ignored). In all cases the first argument can be trivially made NULL. devfs_find_and_unregister() is left as-is. All existing callers converted to new helper - devfs_remove(pathname). Said beast does equivalent of devfs_find_and_unregister(NULL, pathname, 0, 0, 0, 0);

2002-10-15[PATCH] 2.5.43: cpqarray compile fixAdam Kropelin-1/+1
This fixes a recent dyslexicism in cpqarray.
2002-10-15[PATCH] early allocation of ->partAlexander Viro-4/+3
allocation of ->part[] moved to alloc_disk(); alloc_disk() got an argument (number of minors expected). Freeing is in put_disk().
2002-10-08[PATCH] cpqarray SMP deadlock fixAdam Kropelin-9/+8
This fixes some critical bugs in cpqarray in 2.5. One of the fixes essentially backs out the block queue stop/start behavior that was added recently. This code as it stands is buggy and locks up under even light SMP workloads. Certainly we want the performance benefits of proper block queue plugging, but the driver needs some work before it will fit nicely. Some of these fixes do theoretically hurt performance, but when you consider that the driver is unusable under SMP as-is, I think it is right to get correctness first. Specifically, this patch does the following: * Adds locking to proc queue-walking code for debugging use. Note that the proc registration is still broken and I've left it that way since this stuff should probably migrate to driverfs anyway. * Moves interrupt enabling so queue lock is initialized before interrupts are enabled. Otherwise if we get a quick interrupt we oops the machine. * Removes unconditional IRQ enabling in do_ida_request(). The block layer takes the spinlock with irq_save so if we're going to play this trick then we need to irq_restore. For now, just eliminate the unlocked region. * Remove block queue stop/start logic since it can leave the queue stopped with no outstanding completions to start it again. Plugging logic can come back but it should go hand-in-hand with a cleanup of the driver's request handling algorithm. If nobody screams about this patch I'll go ahead and start making those improvments.
2002-10-07[PATCH] cpqarray reads ->irq before pci_enable_device()Dave Jones-5/+4
2002-10-07[PATCH] cpqarray compile fixesAdam Kropelin-1/+0
2002-10-07[PATCH] compile fixesAlexander Viro-1/+1
cpqarray uses disk_alloc instead of alloc_disk. Same typo is in cciss, rd.c sets ->first_minor to 0 for all units and HD_IRQ definition is needed if CONFIG_BLK_DEV_HD is defined.
2002-10-05[PATCH] cpqarray switched to alloc_disk()Alexander Viro-49/+48
In addition to usual switch and cleanup, switched the damn thing to use of module_init/module_exit (and removed call from device_init()).
2002-09-29[PATCH] ->major_name inlinedAlexander Viro-21/+4
char *major_name replaced with char disk_name[16]; All uses of ->major_name replaced with those of ->disk_name and (obviously) simplified big way. Bunch of arrays, kmallocs, etc. is gone.
2002-09-21[PATCH] switch to add_disk()Alexander Viro-10/+4
Almost all callers of add_gendisk() were immediately followed by register_disk(disk, mk_kdev(disk->major,disk->first_minor), 1<<disk->minor_shift, disk->fops, something); The only exception (DAC960.c) massaged to that form. New helper (add_disk(disk)) introduced and aforementioned sequence replaced with set_capacity(disk, something); add_disk(disk);
2002-09-17[PATCH] partial bio completion notificationJens Axboe-2/+4
Make bio->bi_end_io() take bytes_done and actual error as argument. This enables partial completion of bio's, which is important for latency reasons (bio can be huge, for slow media we want page-by-page completions). I think I got most of the bi_end_io() functions out there, but I might have missed a few. For the record, if you don't care about partial completions and just want to be notified when the entire bio completes, add a if (bio->bi_size) return 1; to the top of your bi_end_io(). It should return 0 on completion. bio_endio() will decrement bio->bi_size appropriately, it's recommended for people to go through that. Otherwise they will have to control BIO_UPTODATE and bi_size decrement themselves, there's really no reason to do that. I've deliberately avoided doing any functional changes to any of the end_io functions, as I think that would only make the patch more complex. It's simple right now, but this being i/o paths I prefer (as usual) to be careful and take small steps. The mpage_end_io_read() do-vecs-at-the-time change can come right after this, for instance.
2002-09-07[PATCH] (25/25) more cleanups of struct gendisk.Alexander Viro-9/+1
* we remove the paritition 0 from ->part[] and put the old contents of ->part[0] into gendisk itself; indexes are shifted, obviously. * ->part is allocated at add_gendisk() time and freed at del_gendisk() according to value of ->minor_shift; static arrays of hd_struct are gone from drivers, ditto for manual allocations a-la ide. As the matter of fact, none of the drivers know about struct hd_struct now.
2002-09-07[PATCH] (24/25) disk capacity helpersAlexander Viro-1/+1
new helpers - get_capacity(gendisk)/set_capacity(gendisk, sectors). Drivers switched to these; that eliminates most of the accesses to disk->part[]... in the drivers (and makes code more readable, while we are at it). That had caught several bugs when minor had been used in place of minor>>minor_shift (acsi.c is especially nasty in that respect; I don't know if it had ever been used with multiple devices...)
2002-09-07[PATCH] (8/25) Removing bogus arrays - ->de_arr[]Alexander Viro-8/+5
similar to ->flags and ->driverfs_dev_arr, ->de_arr[] got replaced with its (single) element + flag.
2002-09-07[PATCH] (2/25) Removing ->nr_realAlexander Viro-1/+0
Since ->nr_real is always 1 now, we can remove that field completely. Removed the last remnants of switch in disk_name() (it could be killed a long time ago, I just forgot to remove the last two cases when md and i2o got converted). Collapsed several instances of disk->part[minor - disk->first_minor] - in cases when we know that we deal with disk->part[0].
2002-09-07[PATCH] (1/25) Unexporting helper functionsAlexander Viro-1/+0
wipe_partitions() and driverfs_register_partitions(..., 1) (i.e. unregistering them) pulled into del_gendisk() and removed from callers. grok_partitions() merged with register_disk(). devfs_register_partitions(), grok_partitions() and wipe_partitions() not exported anymore.
