Subject: [PATCH 02/13] autofs: switch to kernel_write
Date: Mon, 15 Jun 2020 14:12:46 +0200 [thread overview]
Message-ID: <20200615121257.798894-3-hch@lst.de> (raw)
In-Reply-To: <20200615121257.798894-1-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.
