Subject: [GIT PULL] f2fs updates for v3.14
Hi Linus,
This is a pull request on f2fs updates for v3.14.
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 also includes a number of clean-ups and several bug
fixes.
Thank you very much.

f2fs: drop obsolete node page when it is truncated (2014-01-23
08:04:21 +0900)
----------------------------------------------------------------
f2fs updates for v3.14
This patch-set includes the following major enhancement patches.
o support inline_data
o refactor bio operations such as merge operations and rw type
assignment
o enhance the direct IO path
o enhance bio operations
o truncate a node page when it becomes obsolete
o add sysfs entries: small_discards, max_victim_search, and
in-place-update
o add a sysfs entry to control max_victim_search
The other bug fixes are as follows.
o fix a bug in truncate_partial_nodes
o avoid warnings during sparse and build process
o fix error handling flows
o fix potential bit overflows
And, there are a bunch of cleanups.
