From 5d22444f427511fe7c4733b233680309af5b071c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 5 Dec 2013 12:28:04 -0500 Subject: [PATCH] cgroup: generalize cgroup_pidlist_open_file In preparation of conversion to kernfs, cgroup file handling is updated so that it can be easily mapped to kernfs. This patch renames cgroup_pidlist_open_file to cgroup_open_file and updates it so that it only contains a field to identify the specific file, ->cfe, and an opaque ->priv pointer. When cgroup is converted to kernfs, this will be replaced by kernfs_open_file which contains about the same information. As whether the file is "cgroup.procs" or "tasks" should now be determined from cgroup_open_file->cfe, the cftype->private for the two files now carry the file type and cgroup_pidlist_start() reads the type through cfe->type->private. This makes the distinction between cgroup_tasks_open() and cgroup_procs_open() unnecessary. cgroup_pidlist_open() is now directly used as the open method. This patch doesn't make any behavior changes. v2: Refreshed on top of the updated "cgroup: introduce struct cgroup_pidlist_open_file".
