Subject: [PATCH 1/2][RESEND] tracing/syscalls: Annotate raw_init function with __init
Date: Thu, 25 Jul 2013 10:27:39 +0800 [thread overview]
Message-ID: <51F08D1B.1080300@huawei.com> (raw)
init_syscall_trace() can be called during kernel bootup only, so we can
mark it and the functions it calls as __init.
