Subject: [git pull v2] device mapper fixes to include in 3.14-rc6

Hi Linus,

Seems you haven't pulled tags/dm-3.14-fixes-2 yet, but either way please
pull tags/dm-3.14-fixes-3

Sorry for requesting that you pull another tag so quickly but a late
breaking yet _very_ important bug fix for dm thin-provisioning and dm
cache has landed based on a really helpful bug report from last night
(see commit cebc2de).

The following changes since commit e0d849fad746cb36a6822e4595d8ba9bf0adf7fa:

  dm cache: fix truncation bug when mapping I/O to >2TB fast device (2014-02-28 09:23:02 -0500)

are available in the git repository at:

  git:// tags/dm-3.14-fixes-3

for you to fetch changes up to cebc2de44d3bce53e46476e774126c298ca2c8a9:

  dm space map metadata: fix refcount decrement below 0 which caused corruption (2014-03-07 12:02:47 -0500)

Please pull, thanks!

A dm-cache memory allocation failure fix, fix DM's Kconfig identation, a
dm-snapshot metadata corruption fix for bug introduced in 3.14-rc1, an
important refcount < 0 fix for the DM persistent data library's space
map metadata interface which fixes corruption reported by a few dm-thinp
users, and last but not least: more extensive fixes than ideal for
dm-thinp's data resize capability (which has had growing pain much like
we've seen from -ENOSPC handling of filesystems that mature).  The end
result is dm-thinp now handles metadata operation failure and no data
space error conditions much better than before.
