Date: Thu, 10 Apr 2014 20:58:52 +0800 From: Jianyu Zhan <nasa4836@...il.com> To: mmarek@...e.cz Cc: akpm@...ux-foundation.org, michael.opdenacker@...e-electrons.com, tkhai@...dex.ru, linux-kernel@...r.kernel.org, nasa4836@...il.com Subject: Re: [PATCH] scripts/tags.sh: add regular expression replacement pattern for memcg Sorry, the comment in previous patch is somewhat misguiding, this patch replaces that one. Currently, no regular expression replacement patterns for PageCgroup* flag-ops are defined, which causes quite a few pain while reading code. Just get rid of it. Also, add a comment to inform people to add pattern for whatever new flag-ops they add.
