Merge tag 'f2fs-for-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "In this round, we've improved the compression support especially for Android such as allowing compression for mmap files, replacing the immutable bit with internal bit to prohibits data writes explicitly, and adding a mount option, "compress_cache", to improve random reads. And, we added "readonly" feature to compact the partition w/ compression enabled, which will be useful for Android RO partitions. Enhancements: - support compression for mmap file - use an f2fs flag instead of IMMUTABLE bit for compression - support RO feature w/ extent_cache - fully support swapfile with file pinning - improve atgc tunability - add nocompress extensions to unselect files for compression Bug fixes: - fix false alaram on iget failure during GC - fix race condition on global pointers when there are multiple f2fs instances - add MODULE_SOFTDEP for initramfs As usual, we've also cleaned up some places for better code readability (e.g., sysfs/feature, debugging messages, slab cache name, and docs)" * tag 'f2fs-for-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (32 commits) f2fs: drop dirty node pages when cp is in error status f2fs: initialize page->private when using for our internal use f2fs: compress: add nocompress extensions support MAINTAINERS: f2fs: update my email address f2fs: remove false alarm on iget failure during GC f2fs: enable extent cache for compression files in read-only f2fs: fix to avoid adding tab before doc section f2fs: introduce f2fs_casefolded_name slab cache f2fs: swap: support migrating swapfile in aligned write mode f2fs: swap: remove dead codes f2fs: compress: add compress_inode to cache compressed blocks f2fs: clean up /sys/fs/f2fs/<disk>/features f2fs: add pin_file in feature list f2fs: Advertise encrypted casefolding in sysfs f2fs: Show casefolding support only when supported f2fs: support RO feature f2fs: logging neatening f2fs: introduce FI_COMPRESS_RELEASED instead of using IMMUTABLE bit f2fs: compress: remove unneeded preallocation f2fs: atgc: export entries for better tunability via sysfs ...
