[PATCH v4] generic: test per-type quota softlimit enforcement timeout

[PATCH v4] generic: test per-type quota softlimit enforcement timeout

[Zorro Lang]

Set different block & inode grace timers for user, group and project
quotas, then test softlimit enforcement timeout, make sure different
grace timers as expected.

Hi,

V4 add a new function filter_enospc_edquot(), to deal with project quota.

After Eric's patch (c8d329f311c4d3d8f8e6dc5897ec235e37f48ae8) merged, xfs has
a fixed return value when project quota is exceeded. But for current linux
kernel, different filesystems have different return value. Some filesystems
return ENOSPC (e.g. XFS), some filsystems return EDQUOT(e.g. ext4). The behavior
isn't definitized. So filter the ENOSPC and EDQUOT output.

Thanks,
Zorro
