Pull f2fs updates from Jaegeuk Kim: "In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata. Enhancements: - add checksum to keep superblock contents more safe - add checkpoint=disable/enable to support A/B update of entire filesystem - use plug for readahead IO in readdir - add more IO counts to avoid block layer hacks Bug fixes: - prevent data corruption issue for hardware encryption - fix IO hang issues when GC is heavily triggered - add missing up_read in __write_node_page - recover inode metadata during roll-forward recovery flow - fix null pointer dereference issue in wrongly configured discard map There are some more sanity checks and minor bug fixes as well" * tag 'f2fs-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (62 commits) f2fs: fix to keep project quota consistent f2fs: guarantee journalled quota data by checkpoint f2fs: cleanup dirty pages if recover failed f2fs: fix data corruption issue with hardware encryption f2fs: fix to recover inode->i_flags of inode block during POR f2fs: spread f2fs_set_inode_flags() f2fs: fix to spread clear_cold_data() Revert "f2fs: fix to clear PG_checked flag in set_page_dirty()" f2fs: account read IOs and use IO counts for is_idle f2fs: fix to account IO correctly for cgroup writeback f2fs: fix to account IO correctly f2fs: remove request_list check in is_idle() f2fs: allow to mount, if quota is failed f2fs: update REQ_TIME in f2fs_cross_rename() f2fs: do not update REQ_TIME in case of error conditions f2fs: remove unneeded disable_nat_bits() f2fs: remove unused sbi->trigger_ssr_threshold f2fs: shrink sbi->sb_lock coverage in set_file_temperature() f2fs: use rb_*_cached friends f2fs: fix to recover cold bit of inode block during POR ...
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
