Subject: [RFC PATCH 05/11] kprobes: Add an KPROBE_FLAG_EARLY for early kprobe.
Date: Wed, 7 Jan 2015 15:35:42 +0800	[thread overview]
Message-ID: <1420616142-42937-1-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1420616086-42692-1-git-send-email-wangnan0@huawei.com>

Introduce a KPROBE_FLAG_EARLY for futher expansion. KPROBE_FLAG_EARLY
indicates a kprobe is installed at very early stage, its resources
should be allocated statically.
