Subject:    [PATCH v3] xfs/288: test xfs_growfs to ensure rejection if target path isn't an active xfs mountpoin
From:       Bill O'Donnell <billodo () redhat ! com>

[Download RAW message or body]

xfs_growfs manpage clearly states that the target path must be an
active xfs mountpoint. This is a test to ensure that if the target
path isn't an active xfs mountpoint, the command is rejected. The
purpose is to check the command response, but not necessarily the
functionality of xfs_growfs. Test cases include absolute paths,
relative paths, symbolic links, and bind mounts.

Signed-off-by: Bill O'Donnell <billodo@redhat.com>

v3: improve commit message and subject line. Use _filter_test_dir
    for absolute pathnames. Use env variable substitutions for
    common fs commands. Send xfs_growfs stdout to /dev/null.
    Remove the use of $tmp.*.
    
v2: acually grow the fs as test proceeds; add filter, preventing
    superfluous stdio verbiage; add test for (unmounted) file; add
    description to commit message to clarify that this isn't a test
    for xfs_growfs functionality, but rather a test of command
    argument accepts and rejections.
