# FS QA Test 382
#
# When default quota is set, all different quota types inherits the
# same default value, include group quota. So if a user quota limit
# larger than the default user quota value, it will still be limited
# by the group default quota value.
#
# There's a patch from Upstream can fix this bug:
#
#    [PATCH] xfs: Split default quota limits by quota type V4
