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.

Thanks for the test! I tested it with 4.10 kernel and test failed. I
assume it's expected result. Some comments inline.

Need _require_scratch, it check if SCRATCH_DEV is present and unmounts
it if so.

Then need to _scratch_mount here.

I always see this message in dmesg, not sure if it affects test?

BTRFS info (device sdc2): qgroup_rescan_init failed with -115

No need to filter & print xfs_io stdout, it makes the .out file not
necessarily too long. We can discard stdout, so if error happens the
stderr output could break the .out file match anyway.

		$XFS_IO_PROG -f -c "pwrite 0 128m" $SUBVOL/file_$j >/dev/null

pwrite error is expected here, and newer xfs_io only prints "pwrite" not
"pwrite64", so _filter_xfs_io_error should be used to filter the error
message from stderr (not stdout).

	$XFS_IO_PROG -f -c "pwrite 0 128m" $SUBVOL/file_$j 2>&1 | _filter_xfs_io_error

Better to add comments about these two for loops, what is the purpose of
each loop etc.

Thanks,
Eryu

Yes, it fails currently. I am trying to get a patch in which fixes this.

-115 is EINPROGRESS, so the scan was initiated earlier so this message
is harmless.

Sound good, this should allow me to make large number of small I/O which
was the original intention.
