Subject: [RFC PATCH 06/11] kprobes: makes kprobes_initialized globally visable.
Date: Wed, 7 Jan 2015 15:35:46 +0800 [thread overview]
Message-ID: <1420616146-42980-1-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1420616086-42692-1-git-send-email-wangnan0@huawei.com>
Following patches will enable kprobe registering very early, before
kprobe system initialized. Arch code can use it to do special treatments
for such kprobes.
