[Intel-gfx] [PATCH 3/5] drm/i915: Force the slow path after a user-write error

[Joonas Lahtinen]

> If we fail to write the user relocation back when it is changed, force
> ourselves to take the slow relocation path where we can handle faults in
> the write path. There is still an element of dubiousness as having
> patched up the batch to use the correct offset, it no longer matches the
> presumed_offset in the relocation, so a second pass may miss any changes
> in layout.
