Subject: [RFC 4/7] move res_counter_set limit to res_counter.c
Date: Fri, 30 Mar 2012 10:04:42 +0200 [thread overview]
Message-ID: <1333094685-5507-5-git-send-email-glommer@parallels.com> (raw)
In-Reply-To: <1333094685-5507-1-git-send-email-glommer-bzQdu9zFT3WakBO8gow8eQ@public.gmane.org>
Preparation patch. Function is about to get complication to be
inline. Move it to the main file for consistency.
