Merge tag 'for-f2fs-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "New features: - in-memory extent_cache - fs_shutdown to test power-off-recovery - use inline_data to store symlink path - show f2fs as a non-misc filesystem Major fixes: - avoid CPU stalls on sync_dirty_dir_inodes - fix some power-off-recovery procedure - fix handling of broken symlink correctly - fix missing dot and dotdot made by sudden power cuts - handle wrong data index during roll-forward recovery - preallocate data blocks for direct_io ... and a bunch of minor bug fixes and cleanups" * tag 'for-f2fs-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (71 commits) f2fs: pass checkpoint reason on roll-forward recovery f2fs: avoid abnormal behavior on broken symlink f2fs: flush symlink path to avoid broken symlink after POR f2fs: change 0 to false for bool type f2fs: do not recover wrong data index f2fs: do not increase link count during recovery f2fs: assign parent's i_mode for empty dir f2fs: add F2FS_INLINE_DOTS to recover missing dot dentries f2fs: fix mismatching lock and unlock pages for roll-forward recovery f2fs: fix sparse warnings f2fs: limit b_size of mapped bh in f2fs_map_bh f2fs: persist system.advise into on-disk inode f2fs: avoid NULL pointer dereference in f2fs_xattr_advise_get f2fs: preallocate fallocated blocks for direct IO f2fs: enable inline data by default f2fs: preserve extent info for extent cache f2fs: initialize extent tree with on-disk extent info of inode f2fs: introduce __{find,grab}_extent_tree f2fs: split set_data_blkaddr from f2fs_update_extent_cache f2fs: enable fast symlink by utilizing inline data ...
