Couple of minor style things....

tmp16 is a bad name for a temporary variable. Move it to the scope
that uses it, and name it for it's purpose. i.e:

Can you fix the flat indenting here at the same time so that the
logic is obvious at a glance and consistent with the rest of the XFS
code? i.e.
if (((flags & XFS_UQUOTA_ACCT) == 0 &&
(mp->m_sb.sb_qflags & XFS_UQUOTA_ACCT) == 0 &&
(flags & XFS_UQUOTA_ENFD)) ||
((flags & XFS_PQUOTA_ACCT) == 0 &&
(mp->m_sb.sb_qflags & XFS_PQUOTA_ACCT) == 0 &&
(flags & XFS_PQUOTA_ENFD)) ||
(flags & XFS_GQUOTA_ACCT) == 0 &&
(mp->m_sb.sb_qflags & XFS_GQUOTA_ACCT) == 0 &&
(flags & XFS_GQUOTA_ENFD))) {

Same here:
if ((!XFS_IS_UQUOTA_ENFORCED(mp) &&
dqp->q_core.d_flags == XFS_DQ_USER) ||
(!XFS_IS_PQUOTA_ENFORCED(mp) &&
dqp->q_core.d_flags == XFS_DQ_PROJ) ||
(!XFS_IS_GQUOTA_ENFORCED(mp) &&
dqp->q_core.d_flags == XFS_DQ_GROUP)) {
Otherwise it looks good. Fix the above and you can add a
