[PATCH] xfs: simplify the flags setting in xfs_qm_scall_quotaon

[xiakaixu1987]

From: Kaixu Xia <kaixuxia@tencent.com>

Simplify the setting of the flags value, and only consider
quota enforcement stuff here.

No idea which function this is.  diff -p, please.

Also, please consider putting all these minor cleanups into a single
patchset, it's a lot easier (for me) to track and land one series than
it is to handle a steady trickle of single patches.

Yeah, the changed function is xfs_qm_scall_quotaon().
Anyway, the result of diff -p as follows,

Yeah, got it. Should I resend all of the patches that have been
reviewed or just resend the last two patches with a single patchset?

The patches that have been reviewed as follows,
xfs: trace quota allocations for all quota types
xfs: combine two if statements with same condition
xfs: check if reserved free disk blocks is needed
xfs: remove unnecessary variable udqp from xfs_ioctl_setattr

The last two patches that have not been reviewed as follow,
xfs: remove unnecessary assertion from xfs_qm_vop_create_dqattach
xfs: simplify the flags setting in xfs_qm_scall_quotaon

That was a request to generate your patches with diff -Naurp.

Got it, I will resend all the patches that have not been applied by
the xfs for-next branch with a single patchset.
