Subject: discard_cache(): discard index, even if no file was mmap()ed
X-Git-Tag: v1.4.3-rc1~174^2~1
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=4147d801db66df9b127ffe315601f467aa9d1c48;p=git.git

discard_cache(): discard index, even if no file was mmap()ed

Since add_cacheinfo() can be called without a mapped index file,
discard_cache() _has_ to discard the entries, even when
cache_mmap == NULL.
