dm stripe: silence a couple sparse warnings (2013-09-06 11:36:01 -0400)
Please pull, thanks.

----------------------------------------------------------------
Add the ability to collect I/O statistics on user-defined regions of a
device-mapper device. This dm-stats code required the reintroduction of
a div64_u64_rem() helper, but as a separate method that doesn't slow
down div64_u64() -- especially on 32-bit systems.
Allow the error target to replace request-based DM devices
(e.g. multipath) in addition to bio-based DM devices.
Various other small code fixes and improvements to thin-provisioning, DM
cache and the DM ioctl interface.
----------------------------------------------------------------
Alasdair Kergon (1):
dm ioctl: prevent rename to empty name or uuid
Carlos Maiolino (1):
dm thin: add data block size limits to Documentation
Joe Thornber (3):
dm btree: use pop_frame in dm_btree_del to cleanup code
dm btree: prefetch child nodes when walking tree for a dm_btree_del
dm space map: optimise sm_ll_dec and sm_ll_inc
Mike Snitzer (13):
dm cache: document metadata device is exclussive to a cache
dm cache: add data block size limits to code and Documentation
dm thin: fix stacking of geometry limits
dm cache: fix stacking of geometry limits
dm cache: eliminate holes in cache structure
math64: New separate div64_u64_rem helper
dm: allow error target to replace bio-based and request-based targets
dm thin: prefix pool error messages with pool device name
dm thin: set pool read-only if breaking_sharing fails block allocation
dm ioctl: increase granularity of type_lock when loading table
dm ioctl: cleanup error handling in table_load
dm thin: always return -ENOSPC if no_free_space is set
dm stripe: silence a couple sparse warnings
Mikulas Patocka (1):
dm: add statistics support
Tejun Heo (1):
dm: stop using WQ_NON_REENTRANT
