# FS QA Test No. 691

# Make sure filesystem quota works well, after soft limits are exceeded. The
# fs quota should allow more space allocation before exceeding hard limits
# and with in grace time.
#
# But different with other similar testing, this case tries to write many small
# files, to cover bc37e4fb5cac (xfs: revert "xfs: actually bump warning counts
# when we send warnings"). If there's a behavior change some day, this case
# might help to detect that too.
