Subject: [RFC PATCH 24/61] fscache: Remove fscache_wait_on_invalidate()
Date: Mon, 04 May 2020 18:11:08 +0100 [thread overview]
Message-ID: <158861226805.340223.17642402641089437416.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <158861203563.340223.7585359869938129395.stgit@warthog.procyon.org.uk>
Remove fscache_wait_on_invalidate() as the invalidation wait is now built into
the I/O path.
