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. Will be fixed by patches with subjects: btrfs: Retry after commit on getting EDQUOT btrfs: Change qgroup_meta_rsv to 64bit Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# create and delete files within the exclusive qgroup limits.
