Subject: Re: [PATCH 3/8] percpu: add __percpu sparse annotations to net
Date: Mon, 25 Jan 2010 13:32:47 -0800 (PST) [thread overview]
Message-ID: <20100125.133247.212571046.davem@davemloft.net> (raw)
In-Reply-To: <1264432935-10453-4-git-send-email-tj@kernel.org>
From: Tejun Heo <tj@kernel.org>
Date: Tue, 26 Jan 2010 00:22:10 +0900
> Add __percpu sparse annotations to net.
>
> These annotations are to make sparse consider percpu variables to be
> in a different address space and warn if accessed without going
> through percpu accessors. This patch doesn't affect normal builds.
>
> The macro and type tricks around snmp stats make things a bit
> interesting. DEFINE/DECLARE_SNMP_STAT() macros mark the target field
> as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly. All
> snmp_mib_*() users which used to cast the argument to (void **) are
> updated to cast it to (void __percpu **).
