-Subject: [PATCH] util/disk_cache: fix size subtraction on 32bit
-
-Negating size_t on 32bit produces a 32bit result. This was effectively
-adding values close to UINT_MAX to the cache size (the files are usually
-small) instead of intended subtraction.
-Fixes 'make check' disk_cache failures on 32bit.
