From 7f2fc81ea26717245fa7e5493a080a9723d6d596 Mon Sep 17 00:00:00 2001 From: Hin-Tak Leung Date: Fri, 6 Jun 2014 14:36:23 -0700 Subject: [PATCH] hfsplus: remove unused routine hfsplus_attr_build_key_uni The directory/file catalog b-tree equivalent, hfsplus_build_key_uni(), is used by hfsplus_find_cat() for internal referencing between catalog records. There is no corresponding usage for attributes - attribute records do not refer to one another.
