[GIT PULL] erofs fixes for 7.4-rc1

[Gao Xiang]

Hi Linus,

Could you consider these extra fixes for 7.4-rc1?

These patches address several new reported issues related to page
cache sharing, the new superblock_share feature, and recent metadata
path changes for file-backed mounts.

All commits have been in linux-next, and no potential merge conflicts
have been observed.

Thanks,
Gao Xiang

 - Fix metadata reads at the end of file-backed images with sub-page
   block sizes

 - Ensure disallowing superblock_share when device= is specified
