From b5d8bbe8601a45b908f7952707bbb30bf221ca3b Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Wed, 11 May 2016 22:51:59 +0900 Subject: [PATCH] perf tools: Use SBUILD_ID_SIZE where applicable Use the existing SBUILD_ID_SIZE macro instead of the equivalent BUILD_ID_SIZE * 2 + 1 expression for allocating a buffer for build-id strings.
