Subject: Re: [PATCH] c/r: Un-blacklist VM_NORESERVE and VM_LOCKED
Date: Fri, 18 Jun 2010 19:49:04 -0700	[thread overview]
Message-ID: <874ogzn3dr.fsf@caffeine.danplanet.com> (raw)
In-Reply-To: <1276897775-4911-1-git-send-email-orenl-eQaUEPhvms7ENvBUuze7eA@public.gmane.org> (Oren Laadan's message of "Fri\, 18 Jun 2010 17\:49\:35 -0400")

OL> Add support for VM_NORESERVE and VM_LOCKED and remove them from
OL> the blacklist of vm flags.

OL> VM_NORESERVE: a vma with VM_NORESERVE may segv on a write under
OL> low-memory, but reading it (as we do during checkpoint) is fine.

OL> VM_LOCKED: this flag is now explicitly restored for a vma that had
OL> this flag, using sys_mlock()

OL> Original patch and reports by Nathan Lynch and Dan Smith.

OL> Signed-off-by: Oren Laadan <orenl-eQaUEPhvms7ENvBUuze7eA@public.gmane.org>

Tested-by: Dan Smith <danms-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>

Thanks :)
