We've added two major features: 1) compression level and 2) checkpoint_merge, in this round. 1) compression level expands 'compress_algorithm' mount option to accept parameter as format of <algorithm>:<level>, by this way, it gives a way to allow user to do more specified config on lz4 and zstd compression level, then f2fs compression can provide higher compress ratio. 2) checkpoint_merge creates a kernel daemon and makes it to merge concurrent checkpoint requests as much as possible to eliminate redundant checkpoint issues. Plus, we can eliminate the sluggish issue caused by slow checkpoint operation when the checkpoint is done in a process context in a cgroup having low i/o budget and cpu shares. Enhancement: - add compress level for lz4 and zstd in mount option - checkpoint_merge mount option - deprecate f2fs_trace_io Bug fix: - flush data when enabling checkpoint back - handle corner cases of mount options - missing ACL update and lock for I_LINKABLE flag - attach FIEMAP_EXTENT_MERGED in f2fs_fiemap - fix potential deadlock in compression flow - fix wrong submit_io condition As usual, we've cleaned up many code flows and fixed minor bugs. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmAtdrAACgkQQBSofoJI UNLvLg//XWERjTZ3tfHHLtNcIkNCd2WaKXwpanTXJsn0kVUc6H5m8lqkutn5Vh/z ZAtQE89aqwbw/FPQQl6jEA/aHhXAnCBbXS0Rjx7QFwlqs+772H10VLvdNXewgvJB r/u7CIlxbmu3p6ZLSG/a8uJe3CMimJe4lrswjnFlLYgKiho40tcQL8qfQEtkNQSF +MV2npS7ka4x/PenFykVbTI0OcwOpblpgkpjgfl5A9bcOsGbli+1qzcasbcX9z9k 20TwZqk5q7rZHVDjvtYERSyS9mmn3fzEJStK4sdZ6uk+EKxyC+KNHrv9cKwemTCm ZATR/YBJKeYhjYppyYLLTRp5eL08PBNgE15SmnkVRjMcAiFxM689WfShrIVhBaf1 dRr9DxAMLuFSiwFuLBLE/8yMwed38RH9e0RrfQRVjj8Zs2kHcUdwD1WqyDg7omS8 NuH776LhJSsSVgC8ZKTacQgX8l2NvsjAigeBj/6v4o0lzr1msn2ADpQ9Bww9Iqtt lv/09350ww78UV+ipLlVSHw4rl8sebatMUSHtmF4SP7U7Jqv2MaGhNAteWlCklmV 0cTzjEueiuvmrmkiphTHtl1fHHDVCE0xtScpoylchPVd8bal0pVq4XbZLmGsQwDt 9V9qOebt2xLmx9EXDyqdRWRbDrtE0FG/AZiN8Q0VcJSzUI/ATx8= =+/7T -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "We've added two major features: 1) compression level and 2) checkpoint_merge, in this round.
