Merge tag 'for-f2fs-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk...

Pull f2fs updates from Jaegeuk Kim:
 "In this round, a couple of sysfs entries were introduced to tune the
  f2fs at runtime.

  In addition, f2fs starts to support inline_data and improves the
  read/write performance in some workloads by refactoring bio-related
  flows.

  This patch-set includes the following major enhancement patches.
   - support inline_data
   - refactor bio operations such as merge operations and rw type
     assignment
   - enhance the direct IO path
   - enhance bio operations
   - truncate a node page when it becomes obsolete
   - add sysfs entries: small_discards, max_victim_search, and
     in-place-update
   - add a sysfs entry to control max_victim_search

  The other bug fixes are as follows.
   - fix a bug in truncate_partial_nodes
   - avoid warnings during sparse and build process
   - fix error handling flows
   - fix potential bit overflows

  And, there are a bunch of cleanups"
