Subject: [PATCH 10/32] fscache: Remove fscache_wait_on_invalidate()
Date: Mon, 13 Jul 2020 17:32:31 +0100 [thread overview]
Message-ID: <159465795136.1376674.599056208279354471.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <159465784033.1376674.18106463693989811037.stgit@warthog.procyon.org.uk>
Remove fscache_wait_on_invalidate() as the invalidation wait is now built into
the I/O path.
