Subject: Delete compat_xtables.ko for being unused
X-Git-Tag: v3.28~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5043d8e81f0c982574b25ff5007c0a0cc4be4e7e;p=thirdparty%2Fxtables-addons.git

Delete compat_xtables.ko for being unused

The use of HX_memmem was rescinded in commit v3.24-6-g30ba7eb .
compat_xtables.ko therefore is unused and can be removed.
