Re: [patch 0/6] fault vs truncate/invalidate race fix

I've also got rid of the horrible populate API, and integrated nonlinear pages
properly with the page fault path.

Downside is that this adds one more vector through which the buffered write
deadlock can occur. However this is just a very tiny one (pte being unmapped
for reclaim), compared to all the other ways that deadlock can occur (unmap,
reclaim, truncate, invalidate). I doubt it will be noticable. At any rate, it
is better than data corruption.

I hope these can get merged (at least into -mm) soon.

Have these been put into mm? can I expect them in the next -mm so I
can start merging up the drm memory manager code to my -mm tree..

Dave.
