pktcdvd: add kobject_put when kobject register fails

2007-12-18T03:28:16Z

In kobject_register, the kobject reference is get in kobject_init, and then kobject_add. If kobject_add fail, it will only cleanup the reference got by itself.

aoe: properly initialise the request_queue's backing_dev_info

2007-12-11T03:43:54Z

AOE forgot to initialise its queue's backing_dev_info, so kernels crash. (http://bugzilla.kernel.org/show_bug.cgi?id=9482) Fix that and consoldate aoeblk_gdalloc()'s error handling.

virtio: fix module/device unloading

2007-11-19T00:20:42Z

The virtio code never hooked through the ->remove callback. Although noone supports device removal at the moment, this code is already needed for module unloading. This of course also revealed bugs in virtio_blk, virtio_net and lguest unloading paths. Signed-off-by: Rusty Russell

rd: fix data corruption on memory pressure

2007-11-15T02:45:42Z

We have seen ramdisk based install systems, where some pages of mapped libraries and programs were suddendly zeroed under memory pressure. This should not happen, as the ramdisk avoids freeing its pages by keeping them dirty all the time. It turns out that there is a case, where the VM makes a ramdisk page clean, without telling the ramdisk driver. On memory pressure shrink_zone runs and it starts to run shrink_active_list. There is a check for buffer_heads_over_limit, and if true, pagevec_strip is called. pagevec_strip calls try_to_release_page. If the mapping has no releasepage callback, try_to_free_buffers is called. try_to_free_buffers has now a special logic for some file systems to make a dirty page clean, if all buffers are clean. Thats what happened in our test case. The simplest solution is to provide a noop-releasepage callback for the ramdisk driver. This avoids try_to_free_buffers for ramdisk pages.

paride: pf driver fixes

2007-11-15T02:45:39Z

The pf driver for parallel port floppy drives seems to be broken. At least with Imation SuperDisk with EPAT chip, the driver calls pi_connect() and pi_disconnect after each transferred sector. At least with EPAT, this operation is very expensive - causes drive recalibration. Thus, transferring even a single byte (dd if=/dev/pf0 of=/dev/null bs=1 count=1) takes 20 seconds, making the driver useless. The pf_next_buf() function seems to be broken as it returns 1 always (except when pf_run is non-zero), causing the loop in do_pf_read_drq (and do_pf_write_drq) to be executed only once. The following patch fixes this problem. It also fixes swapped descriptions in pf_lock() function and removes DBMSG macro, which seems useless.

[NET]: Add the helper kernel_sock_shutdown()

2007-11-13T02:10:39Z

...and fix a couple of bugs in the NBD, CIFS and OCFS2 socket handlers. Looking at the sock->op->shutdown() handlers, it looks as if all of them take a SHUT_RD/SHUT_WR/SHUT_RDWR argument instead of the RCV_SHUTDOWN/SEND_SHUTDOWN arguments. Add a helper, and then define the SHUT_* enum to ensure that kernel users of shutdown() don't get confused.
