[PATCH v4 0/3] staging: erofs: option validation for remount and some code cleanups

[cgxu519@gmx.com (Chengguang Xu)]

Hi Greg, Xiang

I rebased code on latest erofs-master branch and that branch
has already merged the first patch in my previous patchset,
so this time I only post rest 3 patches.

Thanks,

This patch set mainly does option validation for remount and at
the same time does related code cleanups. Currently when we call
fault injection related code we have to surround it with macro
CONFIG_EROFS_FAULT_INJECTION in every calling place, after this
patch set we don't have to do that, so the code looks clean and
more understandable.

v3->v4:
- Rebase code on latest erofs-master branch in Chao's linux tree.
- Fix checkpatch complains.

v2->v3:
- Fold related patches to one patch.
- Fix building issue.

v1->v2:
Address Chao's comments:
- Allow to set fault_injection=0.
- Keep flag bit when setting fault_injection=0.
- Show injection info in original place.
- Rebase code on latest erofs branch in Chao's linux tree.
- Fix building issue.
