Subject: processes plugin: Fix compilation issues under OpenBSD.
X-Git-Tag: collectd-4.5.4~9
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=2d3861c5995b3f39f05495f94143527f95e20ef3;p=collectd.git

processes plugin: Fix compilation issues under OpenBSD.

Unfortunately OpenBSD support is non-trivial to add, so we'll keep that for
later.
