Merge tag 'f2fs-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "In this round, we've introduced fairly small number of patches as below. Enhancements: - improve the in-place-update IO flow - allocate segment to guarantee no GC for pinned files Bug fixes: - fix updatetime in lazytime mode - potential memory leak in f2fs_listxattr - record parent inode number in rename2 correctly - fix deadlock in f2fs_gc along with atomic writes - avoid needless data migration in GC" * tag 'f2fs-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: f2fs: stop GC when the victim becomes fully valid f2fs: expose main_blkaddr in sysfs f2fs: choose hardlimit when softlimit is larger than hardlimit in f2fs_statfs_project() f2fs: Fix deadlock in f2fs_gc() context during atomic files handling f2fs: show f2fs instance in printk_ratelimited f2fs: fix potential overflow f2fs: fix to update dir's i_pino during cross_rename f2fs: support aligned pinned file f2fs: avoid kernel panic on corruption test f2fs: fix wrong description in document f2fs: cache global IPU bio f2fs: fix to avoid memory leakage in f2fs_listxattr f2fs: check total_segments from devices in raw_super f2fs: update multi-dev metadata in resize_fs f2fs: mark recovery flag correctly in read_raw_super_block() f2fs: fix to update time in lazytime mode
