In order to test FAN_FS_ERROR, we want to corrupt the filesystem. The easiest way to do it is by using debugfs. Add a small helper to issue debugfs requests. Since most likely this will be the only testcase to need this, don't bother making it a proper helper for now. Signed-off-by: Gabriel Krisman Bertazi <redacted>
