Christian, Matthew, I think I addressed all review comments and a couple of anticipated ones (s/long/s64/) in the swapout- and eviction patches. I'm heading off on vacation today, (4 weeks) so if something becomes urgent in-between feel free to pick up, modify and merge. Regarding the drm_exec trylock functionality I'm for as much as possible that it should look like any other locking primitive trylock. i.e. no additional tricks needed. Thanks, Thomas
