[Intel-gfx] [PATCH i-g-t 1/3] tests/gem_userptr_blits: More effectively set pages before invalidation

[Janusz Krzysztofik]

It has been observed that mmap-offset-invalidate at wb subtest has never
triggered a lockdep loop complain.  To fix it, don't use the ->domain
field of a mapping type being examined, always set read and write
domains to I915_GEM_DOMAIN_GTT instead.
