Subject: [PATCH 2/2] llvmpipe: keep context list and use to track resource
usage.
Just check across all contexts if a resource is referenced.
Fixes: 6bbbe15a783a ("Reinstate: llvmpipe: allow vertex processing and fragment processing in parallel")
Acked-by: Mike Blumenkrantz <michael.blumenkrantz@gmail.com>
