Subject: mount: Don't stop the mountinfo parser if one line can't be read
X-Git-Tag: v11~10
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1ddff895f3ad85ec79c4923ba8c882a283826f42;p=systemd

mount: Don't stop the mountinfo parser if one line can't be read

The current behavior of the /proc/self/mountinfo parser
is to stop the parser on parse failures

I'm only changing this behavior to try the next line and adding
a warning if occurs a fail.
