[GIT PULL] erofs updates for 6.14-rc1

[Gao Xiang via Linux-erofs <linux-erofs@lists.ozlabs.org>]

Hi Linus,

Could you consider this pull request for 6.14-rc1?

Still no outstanding feature for this cycle, as some ongoing
improvements remain premature for now.

It includes a micro-optimization for the superblock checksum, along
with minor bugfixes and code cleanups, as usual.

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

Thanks,
Gao Xiang
