Subject: unixsock plugin: Make sure the initialization function is run only once.
X-Git-Tag: collectd-4.4.5~10
X-Git-Url: https://git.octo.it/?p=collectd.git;a=commitdiff_plain;h=bc5877df666a8befe63ae4f56fcad849d9c5427a

unixsock plugin: Make sure the initialization function is run only once.

If called multiple times, the global `sock_fd' variable will be re-set,
breaking the plugin.
