Default 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
