+Bugzilla   : 18793
+Descriptoin: OSS complains "too many blocks" and crashes
+Details    : In filter_commitrw_write():
+            1. lquota_chkquota();
+            2. obdo_from_inode();
+            3. lquota_pending_commit();
+            "2." has changed uid and gid in this case, then caused
+            lquota_chkquota() and lquota_pending_commit() to use
+            different uid and gid. That is the root of the bug.
