From 0857bb06065b5c5a51d205c4c04ec1202e27d399 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 15 Apr 2009 23:15:14 +0200 Subject: [PATCH] x86: disable X86_PTRACE_BTS for now upstream commit: d45b41ae8da0f54aec0eebcc6f893ba5f22a1e8e Oleg Nesterov found a couple of races in the ptrace-bts code and fixes are queued up for it but they did not get ready in time for the merge window. We'll merge them in v2.6.31 - until then mark the feature as CONFIG_BROKEN. There's no user-space yet making use of this so it's not a big issue.
