From: Tejun Heo Date: Fri, 29 Nov 2013 15:42:58 +0000 (-0500) Subject: cgroup: introduce struct cgroup_pidlist_open_file X-Git-Tag: v3.14-rc1~136^2~30 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=62236858f3cc558135d1ab6b2af44d22c489bb7f;p=pandora-kernel.git cgroup: introduce struct cgroup_pidlist_open_file For pidlist files, seq_file->private pointed to the loaded cgroup_pidlist; however, pidlist loading is planned to be moved to cgroup_pidlist_start() for kernfs conversion and seq_file->private needs to carry more information from open to allow that. This patch introduces struct cgroup_pidlist_open_file which contains type, cgrp and pidlist and updates pidlist seq_file->private to point to it using seq_open_private() and seq_release_private(). Note that this eventually will be replaced by kernfs_open_file. While this patch makes more information available to seq_file operations, they don't use it yet and this patch doesn't introduce any behavior changes except for allocation of the extra private struct. v2: use __seq_open_private() instead of seq_open_private() for brevity as suggested by Li.
