dm crypt: fix missing error code return from crypt_ctr error path (2015-04-16 22:00:50 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
- Most extensive changes this cycle are the DM core improvements to add
full blk-mq support to request-based DM.
- disabled by default but user can opt-in with CONFIG_DM_MQ_DEFAULT
- depends on some blk-mq changes from Jens' for-4.1/core branch so
that explains why this pull is built on linux-block.git
- Update DM to use name_to_dev_t() rather than open-coding a less
capable device parser.
- includes a couple small improvements to name_to_dev_t() that offer
stricter constraints that DM's code provided.
- Improvements to the dm-cache "mq" cache replacement policy.
- A DM crypt crypt_ctr() error path fix and an async crypto deadlock fix.
- A small efficiency improvement for DM crypt decryption by leveraging
immutable biovecs.
- Add error handling modes for corrupted blocks to DM verity.
- A new "log-writes" DM target from Josef Bacik that is meant for
file system developers to test file system integrity at particular
points in the life of a file system.
- A few DM log userspace cleanups and fixes.
- A few Documentation fixes (for thin, cache, crypt and switch).

Ben Collins (1):
dm crypt: fix deadlock when async crypto algorithm returns -EBUSY
Dan Ehrenberg (3):
init: export name_to_dev_t and mark name argument as const
init: stricter checking of major:minor root= values
dm table: fall back to getting device using name_to_dev_t()
Joe Perches (1):
dm table: use bool function return values of true/false not 1/0
Joe Thornber (5):
dm cache policy mq: keep track of the number of entries in a multiqueue
dm cache policy mq: remove queue_shift_down()
dm cache policy mq: track entries hit this 'tick' via sentinel objects
dm cache policy mq: remove unused generation member of struct entry
dm cache policy mq: try not to writeback data that changed in the last second
Josef Bacik (1):
dm: add log writes target
Mike Snitzer (17):
dm log userspace: split flush_entry_pool to be per dirty-log
dm switch: fix Documentation to use plain text
dm: rename __dm_get_reserved_ios() helper to __dm_get_module_param()
dm: remove unnecessary wrapper around blk_lld_busy
dm: remove request-based DM queue's lld_busy_fn hook
dm: remove request-based logic from make_request_fn wrapper
dm: only run the queue on completion if congested or no requests pending
dm: don't schedule delayed run of the queue if nothing to do
dm: reduce the queue delay used in dm_request_fn from 100ms to 10ms
dm: don't start current request if it would've merged with the previous
dm sysfs: introduce ability to add writable attributes
dm: impose configurable deadline for dm_request_fn's merge heuristic
dm: add full blk-mq support to request-based DM
dm: optimize dm_mq_queue_rq to _not_ use kthread if using pure blk-mq
dm: add 'use_blk_mq' module param and expose in per-device ro sysfs attr
dm thin: remove stale 'trim' message documentation
dm crypt: leverage immutable biovecs when decrypting on read
Milan Broz (1):
dm crypt: update URLs to new cryptsetup project page
Nicholas Mc Guire (3):
dm log userspace transfer: match wait_for_completion_timeout return type
dm log userspace base: fix compile warning
dm delay: use msecs_to_jiffies for time conversion
Sami Tolvanen (1):
dm verity: add error handling modes for corrupted blocks
Wei Yongjun (1):
dm crypt: fix missing error code return from crypt_ctr error path
