Subject: [GIT PULL] f2fs updates for v3.15
Hi Linus,
This is a pull request on f2fs updates for v3.15.
In this round, a couple of sysfs entries were introduced to tune the
f2fs at runtime. In addition, f2fs starts to support large directory and
f2fs_issue_flush thread to improve the performance under some server
workloads.
Most of the other patches are related to bug fixes and clean-ups.
Thank you very much.

f2fs: fix wrong statistics of inline data (2014-04-07 12:40:58 +0900)
----------------------------------------------------------------
f2fs updates for v3.15
This patch-set includes the following major enhancement patches.
o introduce large directory support
o introduce f2fs_issue_flush to merge redundant flush commands
o merge write IOs as much as possible aligned to the segment
o add sysfs entries to tune the f2fs configuration
o use radix_tree for the free_nid_list to reduce in-memory operations
o remove costly bit operations in f2fs_find_entry
o enhance the readahead flow for CP/NAT/SIT/SSA blocks
The other bug fixes are as follows.
o recover xattr node blocks correctly after sudden-power-cut
o fix to calculate the maximum number of node ids
o enhance to handle many error cases
And, there are a bunch of cleanups.
