Merge tag 'for-f2fs-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "Most part of the patches include enhancing the stability and performance of in-memory extent caches feature. In addition, it introduces several new features and configurable points: - F2FS_GOING_DOWN_METAFLUSH ioctl to test power failures - F2FS_IOC_WRITE_CHECKPOINT ioctl to trigger checkpoint by users - background_gc=sync mount option to do gc synchronously - periodic checkpoints - sysfs entry to control readahead blocks for free nids And the following bug fixes have been merged. - fix SSA corruption by collapse/insert_range - correct a couple of gc behaviors - fix the results of f2fs_map_blocks - fix error case handling of volatile/atomic writes" * tag 'for-f2fs-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (54 commits) f2fs: fix to skip shrinking extent nodes f2fs: fix error path of ->symlink f2fs: fix to clear GCed flag for atomic written page f2fs: don't need to submit bio on error case f2fs: fix leakage of inmemory atomic pages f2fs: refactor __find_rev_next_{zero}_bit f2fs: support fiemap for inline_data f2fs: flush dirty data for bmap f2fs: relocate the tracepoint for background_gc f2fs crypto: fix racing of accessing encrypted page among f2fs: export ra_nid_pages to sysfs f2fs: readahead for free nids building f2fs: support lower priority asynchronous readahead in ra_meta_pages f2fs: don't tag REQ_META for temporary non-meta pages f2fs: add a tracepoint for f2fs_read_data_pages f2fs: set GFP_NOFS for grab_cache_page f2fs: fix SSA updates resulting in corruption Revert "f2fs: do not skip dentry block writes" f2fs: add F2FS_GOING_DOWN_METAFLUSH to test power-failure f2fs: merge meta writes as many possible ...
