Subject: Add more comments to _dl_load_cache_lookup().
X-Git-Tag: glibc-2.18~735
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b2d3c3befb45ae4e5284274d9ce75ca462119239;p=thirdparty%2Fglibc.git

Add more comments to _dl_load_cache_lookup().

Calling _dl_load_cache_lookup will load the cache if not already.
If loading the cache fails no more attempts will be made to load
the cache.
