Note that this and future releases now use sources.redhat.com instead of
people.sistina.com (which will be disappearing).
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:
Multipath target
Revision 6:
dm-io
Revision 7:
kcopyd
Revision 8:
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 9:
snapshot target.
Revision 10:
Snapshot: Make calc_max_buckets return a constant 2M for now (need a
proper fix for this). [Chris Mason]
Revision 11:
dm-exception-store: remove dead code. [Dave Olien]
Revision 12:
mirror target.
Revision 13:
Mirror: Exchange slow bit-by-bit count to use hweight32 to count bits per
uint32_t. [AJ Lewis]
Revision 14:
Mirror: flush the log as soon as a region is updated. (Needs
testing).
Revision 15:
Flakey target
Revision 16:
dm-zero
