Subject: dpif-linux: Avoid valgrind warning in epoll_ctl() call.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=733c8d13d7c247245209f9fe54134f35051d3e88;p=openvswitch

dpif-linux: Avoid valgrind warning in epoll_ctl() call.

Valgrind points out correctly that there are uninitialized bytes in the
'event' structure.  That's OK, but it doesn't hurt to suppress the warning
by zeroing all of the bytes.

This doesn't fix a real bug.
