Looks good. But. Since there is repeated calls to mkfs,
-f option might be mandatory. and 265 is indeed working before.
You need to re-phrase the title to the fixes you are bringing in.

There are a few problems with btrfs/265. First we don't redirect the output of
btrfs fi ba somwhere else, so we fail this test outright. Secondly if you have
less than 4 devices in your scratch dev pool it won't work because you can't
mkfs raid10 without 4 devices. This is all impossible to figure out at first
glance because the test redirects all output to /dev/null. So do a few things
1) Redirect all output to $seqres.full to help the next poor sap who finds a
problem.

2) Add an optional option for _require_scratch_dev_pool to specify the minimum
number of devices required to run the test, so you get a nice helpful error
instead of "mkfs failed" in $seqres.full if you don't specify enough devices in
your scratch dev pool.
3) Redirect the output from btrfs fi ba to $seqres.full instead of letting its
output go to stdout and making the test fail anyways.
With these changes this test now passes for me. Thanks,

V1->V2:
-when testing this I had actually had 5 devices in my dev pool so it still
worked, but when I had 4 devices it failed because we strip out the first
device for $SCRATCH_DEV, so fix the math to take this into account and now it
works properly
