Here is the revised version for fixing the infinite loop when turning
quota off but keep user quota being active. After this fix, I ran into another
assertion failure which can be triggered by running fsstress and turning
quota off concurrently.
Since the tests will fail without applying the previous fix:
[PATCH v2] xfs: fix assertion failure at xfs_setattr_nonsize
So I wrapped it up in this series as the 1st fix, maintainers please ignore
another post, the 2nd patch is used to fix the infinite loop, the 3rd one is
to solve the assertion issue.
Since the infinite loop and assertion issue are failed due to different issues,
wonder if we'd better to add two test cases to cover them separately or not?
One sanity check to verify turning group/project off quota with user quota is
another test to verify turning group/project quota off with fsstress is running.
