Subject: Tonnes of new sparse warnings next-20080820
Date: Wed, 20 Aug 2008 13:12:53 -0700	[thread overview]
Message-ID: <1219263173.27981.7.camel@brick> (raw)

All of the form:

include/linux/kmemtrace.h:33:2: warning: cast from restricted gfp_t
The cast to unsigned long will need __force to avoid this warning as
gfp_t is a bitwise type.

include/linux/kmemtrace.h:33:2: warning: Initializer entry defined twice
include/linux/kmemtrace.h:33:2:   also defined here
This occurs at every occurance of trace_mark(), haven't dug into it yet
to fix it.

Dumb-patch for the first warning below:

From: Harvey Harrison <harvey.harrison@gmail.com>
Subject: [PATCH] kmemtrace: gfp_t is a __bitwise_ type, add __force to cast

Fixes sparse warnings of the form:
include/linux/kmemtrace.h:33:2: warning: cast from restricted gfp_t
