Merge tag 'for-f2fs-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "This patch-set includes the following major enhancement patches. - introduce large directory support - introduce f2fs_issue_flush to merge redundant flush commands - merge write IOs as much as possible aligned to the segment - add sysfs entries to tune the f2fs configuration - use radix_tree for the free_nid_list to reduce in-memory operations - remove costly bit operations in f2fs_find_entry - enhance the readahead flow for CP/NAT/SIT/SSA blocks The other bug fixes are as follows: - recover xattr node blocks correctly after sudden-power-cut - fix to calculate the maximum number of node ids - enhance to handle many error cases And, there are a bunch of cleanups" * tag 'for-f2fs-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (62 commits) f2fs: fix wrong statistics of inline data f2fs: check the acl's validity before setting f2fs: introduce f2fs_issue_flush to avoid redundant flush issue f2fs: fix to cover io->bio with io_rwsem f2fs: fix error path when fail to read inline data f2fs: use list_for_each_entry{_safe} for simplyfying code f2fs: avoid free slab cache under spinlock f2fs: avoid unneeded lookup when xattr name length is too long f2fs: avoid unnecessary bio submit when wait page writeback f2fs: return -EIO when node id is not matched f2fs: avoid RECLAIM_FS-ON-W warning f2fs: skip unnecessary node writes during fsync f2fs: introduce fi->i_sem to protect fi's info f2fs: change reclaim rate in percentage f2fs: add missing documentation for dir_level f2fs: remove unnecessary threshold f2fs: throttle the memory footprint with a sysfs entry f2fs: avoid to drop nat entries due to the negative nr_shrink f2fs: call f2fs_wait_on_page_writeback instead of native function f2fs: introduce nr_pages_to_write for segment alignment ...
