In this round, we added a new mount option, "checkpoint_merge", which introduces a kernel thread dealing with the f2fs checkpoints. Once we start to manage the IO priority along with blk-cgroup, the checkpoint operation can be processed in a lower priority under the process context. Since the checkpoint holds all the filesystem operations, we give a higher priority to the checkpoint thread all the time. Enhancement: - introduce gc_merge mount option to introduce a checkpoint thread - improve to run discard thread efficiently - allow modular compression algorithms - expose # of overprivision segments to sysfs - expose runtime compression stat to sysfs Bug fix: - fix OOB memory access by the node id lookup - avoid touching checkpointed data in the checkpoint-disabled mode - fix the resizing flow to avoid kernel panic and race conditions - fix block allocation issues on pinned files - address some swapfile issues - fix hugtask problem and kernel panic during atomic write operations - don't start checkpoint thread in RO And, we've cleaned up some kernel coding style and build warnings. In addition, we fixed some minor race conditions and error handling routines. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmCQhVIACgkQQBSofoJI UNIggA/8DZINzFLMCj6+6P5wNAWj3nYtx/FnwZ7C31f8qkiZjgA4LfONUnDvV7sU GS8MuLQz4eTYfqU2rVgGiSm+aCkEOovnk7C7Huo7pezgqYb+5J6ACXsqdU3dcD5M kShJMqLKcTKqtOMbnJrdGvmw1/ysuAi7UhSSgVV+9NQxlhxADnagOGbQ7lXNSV3R spGMWazGY2uA5DFCCa4lMX79lyFATCzEKB3SKAW5r+8QSmxJY8ViK2Er7AnvwRJz XJ/QJ8ALNb/GGyHzBWFv3P6Yxo/G3FkUvTIc5Rhi9P2lUgjI2NALokj7AOnfNh4a uSXHVlNrrfH+gpx9xr5z8MUmroCYCCOJ6EhnVweqViRmekY8jSb2HxmUtDTIf19U LWl3gtD2GDQx6CY0a0K58Oa2Lp0Bp9MWUdPA/4P21EymZwXum7aCkhV+DnigcoCj yCmKlI8nIpCS97dIO/7MsnG6Tu/7c+Prytd2ezUo+6hlkXPZk8shs+elnjlWu/6V 3ZpSWKzQsPJL8U7eB9H04AxEokrrXm3fRhR86C7JdkEe0gyGFf3dB/G+jqzcNi5m ZpxiCeZ8RbNmPpnH8NWeYHk9uDKMOXuUPFYDoaOwImNWfqj0jfhiTxHo4MyBLAuk MT632ICcuJLvwgnSbMAI3U7v6+dZXKH4y6U7IHFjxhI7beMzxmI= =P5uk -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we added a new mount option, "checkpoint_merge", which introduces a kernel thread dealing with the f2fs checkpoints.
