Subject: ceph_argparse: ignore prefix mismatches, but quit if non-prefix
X-Git-Tag: v0.67-rc1~59^2~5
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=089dfe8e9e98890f14bc824f7b877f209113e46e;p=ceph.git

ceph_argparse: ignore prefix mismatches, but quit if non-prefix

I don't know what I was thinking; this was always the right validation
algorithm, and I broke it trying to simplify.
