When group & project quota got separated, this got missed, and as a result if project quota is enabled and group quota is exceeded, the error code returned is incorrectly returned as ENOSPC not EDQUOT. Fix this by stripping XFS_QMOPT_ENOSPC out of flags for group quota when we try to reserve the space.

The only place we make a decision between -EDQUOT and -ENOSPC returns based on quota type is in xfs_trans_dqresv(). This behavior is currently controlled by whether or not the XFS_QMOPT_ENOSPC flag gets passed into the quota reservation. However, its use is not consistent; paths such as xfs_create() and xfs_symlink() don't set the flag, so a reservation failure will return -EDQUOT for project quota reservation failures rather than -ENOSPC for these sorts of operations, even for project quota: # mkdir mnt/project # xfs_quota -x -c "project -s -p mnt/project 42" mnt # xfs_quota -x -c 'limit -p isoft=2 ihard=3 42' mnt # touch mnt/project/file{1,2,3} touch: cannot touch ‘mnt/project/file3’: Disk quota exceeded We can make this consistent by not requiring the flag to be set at the top of the callchain; instead we can simply test whether we are reserving a project quota with XFS_QM_ISPDQ in xfs_trans_dqresv and if so, return -ENOSPC for that failure. This removes the need for the XFS_QMOPT_ENOSPC altogether and simplifies the code a fair bit.

However, setting an individual grace period is useful; for example: Alice has a soft quota of 100 inodes, and a hard quota of 200 inodes Alice uses 150 inodes, and enters a short grace period Alice really needs to use those 150 inodes past the grace period The administrator extends Alice's grace period until next Monday vfs quota users such as ext4 can do this today, with setquota -T To enable this for XFS, we simply move the timelimit assignment out from under the (id == 0) test. Default setting remains under (id == 0). Note that this now is consistent with how we set warnings. (Userspace requires updates to enable this as well; xfs_quota needs to parse new options, and setquota needs to set appropriate field flags.)
