From: Goldwyn Rodrigues <rgoldwyn@xxxxxxxx>
If we create and delete files within the qgroup limits, qg->reserved
(allocations before commits) over-inflates and causes -EDQUOT to
be returned pre-maturely.
Also, 32/64bit data-type exchanges can cause reserved (u64)
to go negative (very large) and -EDQUOT is returned
pre-maturely.
