Subject: [RFC/PATCH 2/3] init: Initialize jump_labels before early parameters
Date: Fri, 6 Apr 2012 00:03:17 -0700 [thread overview]
Message-ID: <1333695798-2917-3-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1333695798-2917-1-git-send-email-sboyd@codeaurora.org>
We want to use jump_labels in the debug_objects code so that when
debug_objects aren't enabled by default we can skip debug_object
code. Move the jump_label initialization before the early
parameter parsing so that debug_objects code can enable and
disable itself according to kernel command line parameters.

This also opens the window to using static keys for pr_debug().
I tried and wound up in circular dependency hell.
