Merge tag 'for-f2fs-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "The major work includes fixing and enhancing the existing extent_cache feature, which has been well settling down so far and now it becomes a default mount option accordingly. Also, this version newly registers a f2fs memory shrinker to reclaim several objects consumed by a couple of data structures in order to avoid memory pressures. Another new feature is to add ioctl(F2FS_GARBAGE_COLLECT) which triggers a cleaning job explicitly by users. Most of the other patches are to fix bugs occurred in the corner cases across the whole code area" * tag 'for-f2fs-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (85 commits) f2fs: upset segment_info repair f2fs: avoid accessing NULL pointer in f2fs_drop_largest_extent f2fs: update extent tree in batches f2fs: fix to release inode correctly f2fs: handle f2fs_truncate error correctly f2fs: avoid unneeded initializing when converting inline dentry f2fs: atomically set inode->i_flags f2fs: fix wrong pointer access during try_to_free_nids f2fs: use __GFP_NOFAIL to avoid infinite loop f2fs: lookup neighbor extent nodes for merging later f2fs: split __insert_extent_tree_ret for readability f2fs: kill dead code in __insert_extent_tree f2fs: adjust showing of extent cache stat f2fs: add largest/cached stat in extent cache f2fs: fix incorrect mapping for bmap f2fs: add annotation for space utilization of regular/inline dentry f2fs: fix to update cached_en of extent tree properly f2fs: fix typo f2fs: check the node block address of newly allocated nid f2fs: go out for insert_inode_locked failure ...
