Subject: [GIT PULL] erofs fixes for 5.4-rc2

Hi Linus,

Could you consider this pull request for 5.4-rc2?

3 patches of those address regressions due to recent cleanups, mainly
founded by stress test on latest mainline kernel (no more regression
out compared with older kernels for more than a week). The other patch
updates sub-entries in MAINTAINERS.

All commits have been in -next for a week (since 20190924). In order to
avoiding using a random base of a random day, I just rebased those fixes
on -rc1 stable point without any change, which are now in next-20191001
as well. This merges cleanly with master.

This is my first pull request, due to National Day holiday I'd use my
personal email. I refered many other past pull requests these days,
kindly let me know if something wrong...

Thanks,
Gao Xiang
