[GIT PULL] erofs updates for 5.6-rc1

[Gao Xiang]

Hi Linus,

Could you consider this pull request for 5.6-rc1?

A regression fix, several cleanups and (maybe) plus an upcoming
new mount api convert patch as a part of vfs update are considered
available for this cycle.

All commits have been in linux-next and tested with no smoke out.

Thanks,
Gao Xiang
