Subject: [for-next][PATCH 11/12] tracing/kprobes: Remove unnecessary checking of trace_probe_is_enabled
Date: Wed, 19 Jun 2013 23:35:27 -0400 [thread overview]
Message-ID: <20130620033640.219304193@goodmis.org> (raw)
In-Reply-To: 20130620033516.003166252@goodmis.org
[-- Attachment #1: 0011-tracing-kprobes-Remove-unnecessary-checking-of-trace.patch --]
[-- Type: text/plain, Size: 1271 bytes --]
From: "zhangwei(Jovi)" <jovi.zhangwei@huawei.com>
Since tp->flags assignment was moved into function enable_trace_probe(),
there is no need to use trace_probe_is_enabled to check flags
in the same function.
Remove the unnecessary checking.
