Subject: [PATCH] libmount: treat comma as terminator in mnt_match_options()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

An alone "no" in the pattern is interpreted as an error; it should be also
valid in case the keyword is followed by a comma, e.g.

	mnt_match_options("bla", "no,,");
