[GIT PULL] erofs fixes for 6.9-rc7

[Gao Xiang]

Hi Linus,

Could you consider this pull request for 6.9-rc7?

Here are three fixes related to EROFS fscache mode.  The most important
two patches fix calling kill_block_super() in bdev-based mode instead of
kill_anon_super() as mentioned in [1].  The rest patch is an informative
one.

All commits have been in -next and no potential merge conflict is
observed.

Thanks,
Gao Xiang
