Merge branch 'for-3.13/drivers' of git://git.kernel.dk/linux-block

2013-11-14T03:13:05Z

Pull block driver updates from Jens Axboe: "This is the block driver pull request for 3.13. As with the core pull request just sent out, this was rebased on top of the core branch again after the immutable series was pulled. This also means that bcache gets to sit the initial pull over. I will send a second driver pull request in the merge window to get those fixes in, once they have been rebased and tested on top of the non-immutable stack. This pull request contains: - Add support for the sTec Kronos pci-e flash card from sTec. Also has various cleanups for this driver, from myself, Bart, Mike Snizter, and Wei Yongjun. - Add surprise removal support for the micron mtip32xx driver from Micron. - Floppy documentation fix from Ben Harris. - debugfs bug fix for pktcdvd from Dan Carpenter. - Fix for the mtip32xx driver stack usage in the debugfs path, dynamically allocating those buffers instead. From David Milburn. - Disable cpqarray in Kconfig. The plan is to remove it on request of HP, but lets disable it for a few revisions just to see if anyone yells. - drbd fixes from Lars Ellenberg and Philipp Reisner. - Elevator switch fix for the s390 block driver from Heiko Carstens. - loop crash fix on IO to unassigned device from Mikulas Patocka. - A series of bug fixes for the IBM rsxx pci-e flash driver from Philip J Kelleher. - cciss probe fix from Stephen Cameron. - Xen block front/back fixes from Roger Pau Monne and Vegard Nossum" * 'for-3.13/drivers' of git://git.kernel.dk/linux-block: (41 commits) floppy: Correct documentation of driver options when used as a module. pktcdvd: debugfs functions return NULL on error xen-blkfront: restore the non-persistent data path skd: fix formatting in skd_s1120.h skd: reorder construct/destruct code skd: cleanup skd_do_inq_page_da() skd: remove SKD_OMIT_FROM_SRC_DIST ifdefs skd: remove redundant skdev->pdev assignment from skd_pci_probe() skd: use skd: remove SCSI subsystem specific includes skd: register block device only if some devices are present skd: fix error messages in skd_init() skd: fix error paths in skd_init() skd: fix unregister_blkdev() placement skd: more removal of bio-based code skd: cleanup the skd_*() function block wrapping skd: rip out bio path skd: fix error return code in skd_pci_probe() s390/dasd: hold request queue sysfs lock when calling elevator_init() cciss: return 0 from driver probe function on success, not 1 ...

null_blk: multi queue aware block test driver

2013-10-25T10:56:00Z

A driver that simply completes IO it receives, it does no transfers. Written to fascilitate testing of the blk-mq code. It supports various module options to use either bio queueing, rq queueing, or mq mode. Signed-off-by: Jens Axboe

NVMe: Add nvme-scsi.c

Translates SCSI commands in SG_IO ioctl to NVMe commands. Uses the scsi-nvme translation spec from nvmexpress.org as reference. Signed-off-by: Vishal Verma Signed-off-by: Matthew Wilcox

NVMe: Rename nvme.c to nvme-core.c

In preparation for adding nvme-scsi.c It is preferable to retain the module name 'nvme' Signed-off-by: Vishal Verma Signed-off-by: Matthew Wilcox

Merge branch 'delete-xt-disk' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux into for-3.9/drivers

2013-02-14T15:29:34Z

Paul writes: Please pull the following to get the removal of the original IBM PC-XT hard disk driver from the block layer (drivers/block/xd.c). As near as I can tell, it hasn't seen a run time fix in over a dozen years, and with drive sizes of 10-20MB, and performance of about 128kB/s maximum, it is no surprise that it has been completely unused for well over a decade. The removal was originally posted[1] well over a month ago, and since then, there has been nobody objecting to the removal, aside from someone who had mistakenly confused it with a completely different driver (hd.c)

block: IBM RamSan 70/80 device driver

2013-02-05T13:16:05Z

This patch includes the device driver for the IBM RamSan family of PCI SSD flash storage cards. This driver will include support for the RamSan 70 and 80. The driver presents a block device for device I/O. Signed-off-by: Philip J Kelleher Signed-off-by: Jens Axboe

block: delete super ancient PC-XT driver for 1980's hardware

2013-01-05T01:17:40Z

This driver was for the 8 bit ISA cards that were installed in the PC-XT machines of 1980 vintage. They supported the dual ribbon cable MFM drives of 10-20MB capacity, and ran at a 3:1 interleave, giving performance on the order of 128kB/s. By the introduction of the PC-AT (286) these controllers were already scrapped in favour of 16 bit controllers with some onboard RAM that could support a 1:1 interleave. The git history doesn't show any evidence of runtime fixes that would reflect active usage; instead just the usual tree-wide API type changes/cleanups. Going back to in-source changelogs, the last "runtime" fix that is evident is something I did over a dozen years ago[1] -- and even back then, the hardware was long since unavailable, so that ancient fix was also not runtime tested. The time is long overdue for this to get flushed, so lets get rid of it before anyone wastes more time doing builds and sparse checks etc. on long since dead code.
