From 32bff4b9053193303b4dd4c5498a1ffc6b23bb2f Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 29 Nov 2018 14:07:09 +0000 Subject: powerpc/mm: remove unnecessary test in pgtable_cache_init() pgtable_cache_add() gracefully handles the case when a cache that size already exists by returning early with the following test: if (PGT_CACHE(shift)) return; /* Already have a cache of this size */ It is then not needed to test the existence of the cache before.
