From fdce6a4edaada40136f0e61569b938c9a25f61d5 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 22 May 2015 17:42:37 -0300 Subject: [PATCH] perf tools: Remove redundant initialization of thread linkage members A thread moves from a rb tree to a list, but can't be on both, because those linkage members are in a union. This is leftover from when I was debugging thread refcounting and had nuked that union. It is harmless duplication, as RB_CLEAR_NODE() does again what INIT_LIST_HEAD does.
