Hi all,

Still very much early stuff, still very much looking for initial thoughts
and maybe some ideas how this could all be rolled out across drivers.

Full intro probably best from the RFC cover letter:

https://lore.kernel.org/amd-gfx/20200512085944.222637-1-daniel.vetter@ffwll.ch/

Changes since last time around:

- might_sleep annotation has landed already, I split that out as a
  stand-alone

- now with an mm patch to improve direct reclaim annotations for mmu
  notifiers. This allows us to very easily catch issues in that area, no
  more need for exaustive testing and luck to make sure we're not leaving
  a GFP_NOFS or GPF_NOIO around which should be a GFP_ATOMIC

- kerneldoc that explains all the reasoning behind the annotations and
  priming, hopefully

Driver patches still largely just meant as examples to illustrate usage,
but from various irc chats I think discussing them is really useful to
gain clarity on the exact places the annotations should be put.

Cheers, Daniel
