[GIT PULL] nilfs2 changes for 7.3-rc1

Hello Linus,

This pull request contains fixes of syzbot reported issue and
various fixes in NILFS2 functionality.

David Lee implemented rejection of super-root inode sizes
whose computed on-disk footprint exceeds the filesystem
block size.

Igor Putko exchanged WARN_ON() in nilfs_cpfile_delete_checkpoints()
on returning -EIO and reporting a filesystem error via nilfs_error()
in the case of corrupted checkpoint count on the storage medium
because it is suboptimal of interrupting execution with a kernel
warning.

Joshua Crofts has fixed an infinite loop issue in
nilfs_clean_segments() reported by syzbot. In nilfs_clean_segments(),
if err is non-zero, logic logs the error and sleeps but doesn't
abort when it encounters a terminal error like -EROFS. This causes
the thread to loop forever. Fix this by breaking out of the loop
if nilfs_segctor_construct() returns -EROFS.

Manoj K M fixed small grammar mistake in the description
for nilfs2 recovery code.

Ryusuke Konishi has made multiple fixes: (1) fix the list corruption
issue recently detected by syzbot, that can occur when out-of-range
values are intentionally passed to certain GC ioctl parameters;
(2) fix a flaw in the original B-tree implementation related to
truncation and resolves the reported out-of-bounds memory access
issue; (3) fix an issue reported by syzbot where a kernel BUG
could be triggered depending on timing after filesystem
corruption is detected; (4) fix an issue where a WARN_ON
check is triggered by sufile functions within the log writer after
the filesystem degrades to read-only mode.

Wang Jianjian introduced a check for sorted keys when reading
btree node blocks into the cache, preventing unexpected errors
during the block number assignment phase in log writing caused
by key order inconsistencies, as well as the kernel warnings
reported by syzbot.
