Merge tag 'for-f2fs-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
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" * tag 'for-f2fs-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (95 commits) f2fs: drop obsolete node page when it is truncated f2fs: introduce NODE_MAPPING for code consistency f2fs: remove the orphan block page array f2fs: add help function META_MAPPING f2fs: move a branch for code redability f2fs: call mark_inode_dirty to flush dirty pages f2fs: clean checkpatch warnings f2fs: missing REQ_META and REQ_PRIO when sync_meta_pages(META_FLUSH) f2fs: avoid f2fs_balance_fs call during pageout f2fs: add delimiter to seperate name and value in debug phrase f2fs: use spinlock rather than mutex for better speed f2fs: move alloc new orphan node out of lock protection region f2fs: move grabing orphan pages out of protection region f2fs: remove the needless parameter of f2fs_wait_on_page_writeback f2fs: update documents and a MAINTAINERS entry f2fs: add a sysfs entry to control max_victim_search f2fs: improve write performance under frequent fsync calls f2fs: avoid to read inline data except first page f2fs: avoid to left uninitialized data in page when read inline data f2fs: fix truncate_partial_nodes bug ...
