Patches 2 to 6 are now in 2.6.7-rc1-mm1.
Revision 1:
Documentation for the linear target. The last 2 scripts still need
testing.
Revision 2:
dm-ioctl.c: Fix an OB1 error when calculating an output buffer size,
that could cause a missing null termininator in the 'list devices'
ioctl results. [Steffan Paletta]
Revision 3:
In __map_bio(), if the target returns an error while mapping the I/O, the
cloned bio needs to be freed.
Revision 4:
Replace dm_[add|remove]_wait_queue() with dm_wait_event().
Some testing of DM multipath has turned up a problem with the DEVICE_WAIT
command. In the tests, while performing a DEVICE_WAIT on a multipath device,
the command sometimes returns immediately, even though the event-number is
correct and no path-failure has occurred to trigger an event. The problem
was tracked down to the call to schedule() in dev_wait(), which would return
even though it was not woken up by a DM table event.
This patch moves the responsibility for waiting from the ioctl interface into
the core driver, and uses wait_event_interruptible() instead of relying on
wait-queues and schedule().
Revision 5:
DM: Add static and __init qualifiers. [Dave Olien]
Revision 6:
dm-table.c: Proper usage of dm_vcalloc. [Dave Olien]
Revision 7:
Multipath target
Revision 8:
dm-io
Revision 9:
dm-io.c:
- Add static qualifiers
- Export dm_io_sync_bvec
[Dave Olien]
Revision 10:
kcopyd
Revision 11:
Force kcopyd to be single-threaded. For now, snapshotting cannot handle
multiple kcopyd threads. When we determine the correct way to make snapshot
safe for a multithreaded kcopyd, this patch can be removed.
Revision 12:
kcopyd: Add __init qualifier. [Dave Olien]
Revision 13:
snapshot target.
Revision 14:
Snapshot: Make calc_max_buckets return a constant 2M for now (need a
proper fix for this). [Chris Mason]
Revision 15:
dm-exception-store: remove dead code. [Dave Olien]
Revision 16:
dm-snapshot: Add static qualifiers. [Dave Olien]
Revision 17:
dm-snap.c: Remove check_free_space()
Revision 18:
dm-snap.c: Remove old DEBUG log statements.
Revision 19:
dm-snap.c: Remove old FIXME comments.
Revision 20:
mirror target.
Revision 21:
Mirror: Exchange slow bit-by-bit count to use hweight32 to count bits per
uint32_t. [AJ Lewis]
Revision 22:
Mirror: flush the log as soon as a region is updated. (Needs
testing).
Revision 23:
dm-log.c:
- Check return value from try_module_get().
- Add .module field to dirty_log_type struct.
- Add __init qualifier.
- Don't need to export init and exit routines.
[Dave Olien]
Revision 24:
Flakey target
Revision 25:
dm-flakey.c: Add __exit qualfier. [Dave Olien]
Revision 26:
dm-zero
Revision 27:
dm-multipath: ps-refcount.patch
Fixes the refcounting on the path-selectors. And, exports the
register/unregister functions.
[Mike Christie]
Revision 28:
dm-multipath: mv-path-code-to-ps.patch
Some path-selectors will want to choose paths that have a couple of failed
IOs vs always failing paths with X number of failures. Also some path-
selectors will want to select a path by detecting congestion or some other
determination than X bios have been sent.
[Mike Christie]
Revision 29:
dm-multipath: ps-init-fn.patch
This adds the ps-init function.
[Mike Christie]
Revision 30:
dm-snap.c: Remove unnecessary BUG. If no snapshots are found for an origin
device, just submit the I/O without any extra processing.
