Merge tag 'for-f2fs-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "In this round, we've investigated how f2fs deals with errors given by our fault injection facility. With this, we could fix several corner cases. And, in order to improve the performance, we set inline_dentry by default and enhance the exisiting discard issue flow. In addition, we added f2fs_migrate_page for better memory management. Enhancements: - set inline_dentry by default - improve discard issue flow - add more fault injection cases in f2fs - allow block preallocation for encrypted files - introduce migrate_page callback function - avoid truncating the next direct node block at every checkpoint Bug fixes: - set page flag correctly between write_begin and write_end - missing error handling cases detected by fault injection - preallocate blocks regarding to 4KB alignement correctly - dentry and filename handling of encryption - lost xattrs of directories" * tag 'for-f2fs-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (69 commits) f2fs: introduce update_ckpt_flags to clean up f2fs: don't submit irrelevant page f2fs: fix to commit bio cache after flushing node pages f2fs: introduce get_checkpoint_version for cleanup f2fs: remove dead variable f2fs: remove redundant io plug f2fs: support checkpoint error injection f2fs: fix to recover old fault injection config in ->remount_fs f2fs: do fault injection initialization in default_options f2fs: remove redundant value definition f2fs: support configuring fault injection per superblock f2fs: adjust display format of segment bit f2fs: remove dirty inode pages in error path f2fs: do not unnecessarily null-terminate encrypted symlink data f2fs: handle errors during recover_orphan_inodes f2fs: avoid gc in cp_error case f2fs: should put_page for summary page f2fs: assign return value in f2fs_gc f2fs: add customized migrate_page callback f2fs: introduce cp_lock to protect updating of ckpt_flags ...
