Index:
This patch adds a spot in the task record to save the personality value
of the task_struct.
It also masks out READ_IMPLIES_EXEC before starting to avoid read-only
maps being restored as read-exec. To avoid re-setting this flag too early,
it also introduces a task_ctx object to hold information

Add start argument, it will be used to map vDSO to exactly same place
on restart(2).

IIRC the first (bprm) argument is actually completely unused. So in my
version of this patch (in mid-march)

Hi,
I have a few question.
- I have not yet fully understood how your controller are using
bio_cgroup. If my view is wrong please tell me.
o In my view, bio_cgroup's implementation strongly depends on
page_cgoup's. Could you explain for what purpose does this
functionality itself
* Andrew Morton a...@linux-foundation.org [2009-04-16 17:44:28]:
Hmm, how about iotrack-cgroup ?
Well. blockio_cgroup has the same character count and is more specific.
Sounds good to me.
