Subject: [PATCH 3/9] watch_queue: Drop references to /dev/watch_queue
Date: Fri, 27 Nov 2020 16:45:47 +0000 [thread overview]
Message-ID: <160649554788.2744658.2677540173062709534.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <160649552401.2744658.15096366594785577090.stgit@warthog.procyon.org.uk>
From: Gabriel Krisman Bertazi <krisman@collabora.com>
The merged API doesn't use a watch_queue device, but instead relies on
pipes, so let the documentation reflect that.
Fixes: f7e47677e39a ("watch_queue: Add a key/keyring notification facility")
