[ofa-general] Re: [PATCH 02 of 11] get_task_mm

[Robin Holt]

You can drop this patch.

This turned out to be a race in xpmem.  It "appeared" as if it were a
race in get_task_mm, but it really is not.  The current->mm field is
cleared under the task_lock and the task_lock is grabbed by get_task_mm.

I have been testing you v15 version without this patch and not
encountere the problem again (now that I fixed my xpmem race).

Thanks,
Robin
