Series drm/i915: Remove obj->mm.lock! | expand

Commit Message

Maarten Lankhorst Jan. 5, 2021, 3:35 p.m. UTC
We want to remove the changing of ops structure for attaching
phys pages, so we need to kill off HAS_STRUCT_PAGE from ops->flags,
and put it in the bo.

This will remove a potential race of dereferencing the wrong obj->ops
without ww mutex held.
