gfs2: move privileged user check to gfs2_quota_lock_check
Before this patch, function gfs2_quota_lock checked if it was called from a privileged user, and if so, it bypassed the quota check: superuser can operate outside the quotas. That's the wrong place for the check because the lock/unlock functions are separate from the lock_check function, and you can do lock and unlock without actually checking the quotas. This patch moves the check to gfs2_quota_lock_check. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
