I haven't expected that anyone who haven't already participated in the discussion about CMA and VCMM will get interested by this patchset so I was a bit vague in the cover letter.

Ignore the code then and look just at the documentation, please. I wanted to post what I have to receive comments about the general idea and not necessarily the code itself. Code is just a mean to show how I see the implementation of the idea described in the documentation.= Because of all that, I marked the patchset as a RFC rather than a PATCH.= -- = Best regards, _ _ | Humble Liege of Serenely Enlightened Majesty of o' \,=3D./ `o | Computer Science, Micha=C5=82 "mina86" Nazarewicz (o o) +----[mina86*mina86.com]---[mina86*jabber.org]----ooO--(_)--Ooo-- -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
