Subject: vlog: Send multi-line log messages to syslog() one line at a time.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=42c89afbde5e0c59e1ddd92c9f81a5a969cb19a3;p=openvswitch

vlog: Send multi-line log messages to syslog() one line at a time.

syslogd swallows new-lines, which makes multi-line messages otherwise
difficult to read.
