Subject: [for-next][PATCH 2/5] tracing/syscalls: Annotate raw_init function with __init
Date: Thu, 22 Aug 2013 12:32:27 -0400 [thread overview]
Message-ID: <20130822163420.330586243@goodmis.org> (raw)
In-Reply-To: 20130822163225.773134216@goodmis.org
[-- Attachment #1: 0001-tracing-syscalls-Annotate-raw_init-function-with-__i.patch --]
[-- Type: text/plain, Size: 1850 bytes --]
From: Li Zefan <lizefan@huawei.com>
init_syscall_trace() can only be called during kernel bootup only, so we can
mark it and the functions it calls as __init.
