Subject: [PATCH 01/26] bpfilter: fix up a sparse annotation
Date: Thu, 23 Jul 2020 08:08:43 +0200
Message-ID: <20200723060908.50081-2-hch@lst.de> (raw)
In-Reply-To: <20200723060908.50081-1-hch@lst.de>

The __user doesn't make sense when casting to an integer type, just
switch to a uintptr_t cast which also removes the need for the __force.
