# FS QA Test No. 157
#
# Functional testing for xfs_admin to ensure that it parses arguments correctly
# with regards to data devices that are files, external logs, and realtime
# devices.
#
# Because this test synthesizes log and rt devices (by modifying the test run
# configuration), it does /not/ require the ability to mount the scratch
# filesystem.  This increases test coverage while isolating the weird bits to a
# single test.
#
# This is partially a regression test for "xfs_admin: pick up log arguments
# correctly", insofar as the issue fixed by that patch was discovered with an
# earlier revision of this test.
