Subject: libceph: stop parsing when a bad int arg is detected
Git-commit: 17173c82e3daa28742bf7732520e9bc2e0cb977d
Patch-mainline: v4.19-rc1
References: FATE#324714
There is no reason to continue option parsing after detecting
bad option.
[ Return match_int() errors from ceph_parse_options() to match the
behaviour of parse_rbd_opts_token() and parse_fsopt_token(). ]
