Subject: [GIT PULL] erofs fixes for 6.5-rc5

Hi Linus,

Sorry about another pull due to new reports this cycle, but could you
consider these two patches for 6.5-rc5?

One patch addresses a data corruption of compressed data deduplication
reported by Shijie Sun who is using this feature in their products.

The other one actually drops a useless WARN_ON() in erofs_kill_sb().
Since the commit is trivial and the WARN_ON() was actually broken in
the -next tree (and triggered a syzbot report) due to a behavior change
of .kill_sb() for the next cycle, it'd be better to fix it upstream now.

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

Thanks,
Gao Xiang
