[Mesa-dev] [PATCH v2 1/7] util/disk_cache: use a helper to compute cache keys

Wed Mar 15 23:09:27 UTC 2017
This will allow to hash additional data into the cache keys or even
change the hashing algorithm easily, should we decide to do so.
v2: don't try to compute key (and crash) if cache is disabled
