[git pull] 3.6 device-mapper fixes

[Alasdair G Kergon]

Please pull from:
 
  git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm tags/dm-3.6-fixes
 
to get the following device-mapper fixes.

----------------------------------------------------------------
A few fixes for problems discovered during the 3.6 cycle.

Of particular note, are fixes to the thin target's discard support,
which I hope is finally working correctly; and fixes for multipath
ioctls and device limits when there are no paths.

----------------------------------------------------------------
Mike Snitzer (6):
      dm thin: do not set discard_zeroes_data
      dm mpath: only retry ioctl when no paths if queue_if_no_path set
      dm: handle requests beyond end of device instead of using BUG_ON
      dm: retain table limits when swapping to new table with no devices
      dm thin: tidy discard support
      dm thin: fix discard support for data devices

Mikulas Patocka (1):
      dm verity: fix overflow check

Milan Broz (1):
      dm table: clear add_random unless all devices have it set
