Subject: [for-next][PATCH 4/4] tracing: Add entry->next_cpu to trace_ctxwake_bin()
Date: Tue, 04 Nov 2014 08:48:51 -0500 [thread overview]
Message-ID: <20141104134916.450863338@goodmis.org> (raw)
In-Reply-To: 20141104134847.978505265@goodmis.org
[-- Attachment #1: 0004-tracing-Add-entry-next_cpu-to-trace_ctxwake_bin.patch --]
[-- Type: text/plain, Size: 987 bytes --]
From: Jiang Liu <jiang.liu@huawei.com>
Function trace_ctxwake_bin() misses ctx_switch_entry->next_cpu field,
so user will get stale value for "next_cpu".
