From fe1217c4f3f7d7cbf8efdd8dd5fdc7204a1d65a8 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Sun, 29 Dec 2013 18:27:10 +0100 Subject: net: net_cls: move cgroupfs classid handling into core Zefan Li requested [1] to perform the following cleanup/refactoring: - Split cgroupfs classid handling into net core to better express a possible more generic use. - Disable module support for cgroupfs bits as the majority of other cgroupfs subsystems do not have that, and seems to be not wished from cgroup side. Zefan probably might want to follow-up for netprio later on. - By this, code can be further reduced which previously took care of functionality built when compiled as module. cgroupfs bits are being placed under net/core/netclassid_cgroup.c, so that we are consistent with {netclassid,netprio}_cgroup naming that is under net/core/ as suggested by Zefan. No change in functionality, but only code refactoring that is being done here.

This not only makes the CONFIG option consistent among networking cgroups, but also among cgroups CONFIG conventions in general as the vast majority has a prefix of CONFIG_CGROUP_.
