Subject: [PATCH 03/14] bpfilter: switch to kernel_write
Date: Wed, 13 May 2020 08:56:45 +0200	[thread overview]
Message-ID: <20200513065656.2110441-4-hch@lst.de> (raw)
In-Reply-To: <20200513065656.2110441-1-hch@lst.de>

While pipes don't really need sb_writers projection, __kernel_write is an
interface better kept private, and the additional rw_verify_area does not
hurt here.
