Subject: cfg: Initialize lock_fd to -1.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=00034713a99b1fbc353699fe779360960eeca6a6;p=openvswitch

cfg: Initialize lock_fd to -1.

Otherwise cfg_unlock() will close stdin on the first call.  Since
create_lockfile() calls remove_lockfile() as its first action, that's
on every useful execution.
