Subject: [PATCH 1/2] tracing/syscalls: Annotate raw_init function with __init
Date: Wed, 27 Mar 2013 14:15:37 +0800 [thread overview]
Message-ID: <51528E89.6080508@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.
