Subject: [for-next][PATCH 04/18] x86/kvm/tracing: Use helper function trace_seq_buffer_ptr()
Date: Wed, 19 Nov 2014 18:26:36 -0500 [thread overview]
Message-ID: <20141119232709.907008577@goodmis.org> (raw)
In-Reply-To: 20141119232632.737569526@goodmis.org
[-- Attachment #1: 0004-x86-kvm-tracing-Use-helper-function-trace_seq_buffer.patch --]
[-- Type: text/plain, Size: 1432 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
To allow for the restructiong of the trace_seq code, we need users
of it to use the helper functions instead of accessing the internals
of the trace_seq structure itself.
