Default Further device-mapper fixes for 3.5

Please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm tags/dm-3.5-fixes-2

to get the following further device-mapper fixes for 3.5.


Three fixes for device-mapper discard processing:
- avoid a crash in dm-raid1 when discards coincide with mirror recovery;
- avoid discarding shared data that's still needed in dm-thin;
- don't guarantee that discarded blocks will be wiped in dm-raid1.

Mikulas Patocka (3):
dm raid1: fix crash with mirror recovery and discard
dm thin: do not send discards to shared blocks
dm raid1: set discard_zeroes_data_unsupported
