-Some BIOS's don't setup power management correctly (what else is
-new) and don't allow use of PCI Express power control. Add a special
-exception module parameter to allow working around this issue.
-Based on slightly different patch by Knut Petersen.

+Basically this is a copy of commit 001e4a8775f6(ext4: implement cgroup
+writeback support). Tested with a fio test, verified writeback is
+throttled against cgroup io.max write bandwidth, also verified moving
+the fio test to another cgroup and the writeback is throttled against
+new cgroup setting.

-Subject: [PATCH] proc: fix mount -t proc -o AAA
-
-proc_parse_options() inside of proc_mount() runs only once at the boot
-time without any given options. So, following umount(2)+mount(2) ignore
-mount options: proc_parse_options() is not called as ->s_root is already
-initialized. To fix that parse mount options unconditionally.
