Hey Linus,
/* Summary */
This contains two follow-up fixes for the super work this cycle:
* Move a misplaced lockep assertion before we potentially free the
object containing the lock.
* Ensure that filesystems which match superblocks in sget{_fc}() based
on sb->s_fs_info are guaranteed to see a valid sb->s_fs_info as long
as a superblock still appears on the filesystem type's superblock
list.
What we want as a proper solution for next cycle is to split
sb->free_sb() out of sb->kill_sb() so that we can simply call
kill_super_notify() after sb->kill_sb() but before sb->free_sb().
Currently, this is lumped together in sb->kill_sb().
/* Testing */
clang: Ubuntu clang version 15.0.7
gcc: (Ubuntu 12.2.0-3ubuntu1) 12.2.0
All patches are based on v6.6-vfs.super and have been sitting in
linux-next. No build failures or warnings were observed. All old and new
tests in selftests, and LTP pass without regressions.
/* Conflicts */
At the time of creating this PR no merge conflicts were reported from
linux-next and no merge conflicts showed up doing a test-merge with
current mainline.
