No need to test for the truncate command as it's supported in all
versions of xfs_io people use. falloc, OTOH, isn't supported on oler
distros that people still need to run QA on, and hence that check is
required....

$SCRATCH_MNT is not mounted at this point. The test needs to go
after _scratch_mkfs/_scratch_mount...
Hmmm - I'm thinking this should really be a "_requires_batched_discard"
function. It already internally calls _require_fstrim, so we should
just drive everything inwards. i.e.:
_require_batched_discard()
{
if [ $# -ne 1 ]; then
echo "Usage: _require_batched_discard mnt_point" 1>&2
exit 1
fi
_require_fstrim
[ $FSTRIM_PROG $1 > /dev/null 2>&1 ] || \
_notrun "FITRIM not supported on $1"
}
And so not even need the _requires_fstrim call in these tests...
Cheers,
Dave.
