And into tests/generic. Tests were found simply by grepping for the __supported_fs field in the tests. Output starts to look like: $ sudo ./check -g quick -r FSTYP -- xfs (debug) PLATFORM -- Linux/x86_64 test-1 3.5.0-rc5-dgc+ MKFS_OPTIONS -- -f -bsize=4096 /dev/vdb MOUNT_OPTIONS -- /dev/vdb /mnt/scratch ./242 1s ./183 2s generic/236 1s generic/014 1s generic/258 0s ./096 1s generic/245 0s ^C Ran: ./242 ./183 generic/236 generic/014 generic/258 ./096 generic/245 Passed all 7 tests Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Phil White <pwhite@sgi.com> [rjohnston@sgi.com added TOT changes] Signed-off-by: Rich Johnston <rjohnston@sgi.com>

# FS QA Test No. 260

#
|
|
# Purpose of this test is to check FITRIM argument handling to make sure
|
|
# that the argument processing is right and that it does not overflow.
