Revision 1:
-mm2
Revision 2:
-mm2 errata
Revision 3:
If there are leftovers __end_that_request_first will call
blk_recalc_rq_sector to set req->hard_nr_sectors correctly.
For failfast, by subtracting bytes from the updated
req->hard_nr_sectors and then calling end_that_request_chunk
and end_that_request_last, you can end up with a bio that
never gets completed.
The attached patch built against 2.6.4 does not subtract
bytes for non-blk_pc_requests.
On a related note I was wondering if the following is a
bug or feature. At the bottom of scsi_io_completion, it calls
scsi_end_request on the bytes for the current buffer.
The comments indicate this is to handle improperly reported
medium errors, but commands scsi_decide_disposition
determined should not be retried end up getting
requeued minus the current buffer. [Mike Christie]
Revision 4:
Fix 64/32 bit ioctl problems.
Revision 5:
dm-ioctl.h: Missing definition for DM_LIST_VERSIONS_32.
Revision 6:
Check the uptodate flag in sub-bios to see if there was an error.
[Mike Christie]
Revision 7:
Handle interrupts within suspend.
Revision 8:
dm.c: Use waitqueue_active() to save a couple of cycles.
I couldn't think of a reason why event_callback() was using
wake_up_interruptible() rather than plain old wake_up(), so changed
it.
Revision 9:
VFS lock patch. [Chris Mason]
Revision 10:
Lock the filesystem while a device is suspended. [Kevin Corry, Joe Thornber]
Revision 11:
Multipath target
Revision 12:
dm-mpath.c: Remove blk_run_queues() after resubmitting failed ios.
Revision 13:
dm-io
Revision 14:
dm-io: stop using page->list
Revision 15:
dm-io.c: Add io routines to perform io on a vm area.
Revision 16:
dm-io.c: Get rid of global queues unplug. [Jens Axboe]
Revision 17:
dm-io.c: Add EXPORT_SYMBOL for dm_io_async_vm() and dm_io_sync_vm().
[Kevin Corry]
Revision 18:
kcopyd
Revision 19:
kcopyd: stop using page->list
Revision 20:
kcopyd.c: Remove blk_run_queues(). [Jens Axboe]
Revision 21:
kcopyd.c: kcopyd_put_pages() does not walk the entire list of
specified pages (it stops at the second-to-last one). Thus, the
nr_free_pages value is off by one. Fix this by incrementing
nr_free_pages once more after the loop completes. [Kevin Corry]
Revision 22:
Snapshot target
Revision 23:
dm-exception-store.c: Use these routines.
Revision 24:
dm-snap.c: Remove blk_run_queues() from flush_bios(). (Not sure about
this).
Revision 25:
Mirror target
Revision 26:
dm-log.c: Switch from using dm_io_sync() to dm_io_sync_vm().
Revision 27:
dm-raid1.c: Remove blk_run_queues().
Revision 28:
Flakey target
Revision 29:
dm-zero
Revision 30:
Log an error if the target has unknown target type, or zero length.
