From df292c791ab790340cc9e3577a073bcb9d1900ea Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 21 Mar 2008 15:53:00 -0700 Subject: [PATCH] Make "index_name_exists()" return the cache_entry it found This allows verify_absent() in unpack_trees() to use the hash chains rather than looking it up using the binary search. Perhaps more importantly, it's also going to be useful for the next phase, where we actually start looking at the cache entry when we do case-insensitive lookups and checking the result.
