Subject: swap plugin: Remove the swap_submit() function.
X-Git-Tag: collectd-5.5.0~316^2~9^2
X-Git-Url: https://git.octo.it/?p=collectd.git;a=commitdiff_plain;h=60b9a6ea2ffec1e9a2f0a042212224f8937611ac

swap plugin: Remove the swap_submit() function.

This function was used only by swap_submit_derive(), which was declared
conditionally. This resulted in "defined but not used" warnings, e.g. on
FreeBSD.
