Subject: memory plugin: Fix the order of the #ifdef's.
X-Git-Tag: collectd-4.7.0~41
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=38f27d544d9dec62d9aa382098507d8fc36c61f8;p=collectd.git

memory plugin: Fix the order of the #ifdef's.

Linux has sysctl too. I'm using the same order as in the CPU plugin here,
i. e.:
 * Linux
 * kstat
 * sysctl
