quoted hunk ↗ jump to hunk
At the moment we're leaking the GEM and FB objects that could lead to
OOM if multiple subtests are run (vs. each subtest in a seperate test

I guess this gem_close could be called before doing asserts.

These igt_remove_fb could be called unconditionally, they do as first

those are just minor comments, fix or no fix either way
