Subject: [GIT PULL] erofs fixes for 6.5-rc2

Hi Linus,

Could you consider these patches for 6.5-rc2?

Three patches address regressions related to post-EOF unexpected
behaviors and fsdax unavailability of chunk-based regular files.

The other two patches mainly get rid of kmap_atomic() and simplify
z_erofs_transform_plain() which I think they are simple enough to
be addressed in this cycle.

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

Thanks,
Gao Xiang
