Subject: [PATCH 03/14] bpfilter: switch to kernel_write
Date: Wed, 24 Jun 2020 18:13:24 +0200 [thread overview]
Message-ID: <20200624161335.1810359-4-hch@lst.de> (raw)
In-Reply-To: <20200624161335.1810359-1-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.
