[dm-devel] [git pull] device-mapper patches for 2.6.36

[Resent with mailing lists I lost from the cc - again...]

Please pull from:

  master.kernel.org:/pub/scm/linux/kernel/git/agk/linux-2.6-dm.git master

to get the following device-mapper fixes and enhancements for inclusion in

The main enhancement here is discard support.  We left the dm-crypt target out
of this for now, hoping we might find some cryptographers to help us consider
Alasdair G Kergon (3):
      dm mpath: fix NULL pointer dereference when path parameters missing
      dm ioctl: make __dev_status void
      dm: use dm_target_offset macro

Arnd Bergmann (1):
      dm ioctl: use nonseekable_open

Julia Lawall (1):
      dm crypt: use kstrdup

Kiyoshi Ueda (3):
      dm: prevent access to md being deleted
      dm ioctl: release _hash_lock between devices in remove_all
      dm: separate device deletion from dm_put

Mike Snitzer (11):
      dm ioctl: make bio or request based device type immutable
      dm: do not initialise full request queue when bio based
      dm: rename map_info flush_request to target_request_nr
      dm: linear support discard
      dm: use common __issue_target_request for flush and discard support
      dm: factor out max_io_len_target_boundary
      dm: zero silently drop discards
      dm delay: support discard
      dm: error return error for discards
      dm: split discard requests on target boundaries
      dm mpath: support discard

Mikulas Patocka (7):
      dm snapshot: iterate origin and cow devices
      dm snapshot: test chunk size against both origin and snapshot
      dm: skip second flush on bio unsupported error
      dm snapshot: implement merge
      dm stripe: move sector translation to a function
      dm stripe: optimize sector division
      dm stripe: support discards

Milan Broz (2):
      dm crypt: simplify crypt_config destruction logic
      dm crypt: simplify crypt_ctr

Peter Rajnoha (3):
      dm ioctl: remove __dev_status from geometry and target message
      dm ioctl: return uevent flag after rename
      dm: allow autoloading of dm mod

Tomohiro Kusumi (1):
      dm snapshot: persistent use define for disk header chunk size

Will Drewry (1):
      dm ioctl: refactor dm_table_complete
