Subject: [PATCH 12/67] fscache: Remove obsolete stats
Date: Mon, 18 Oct 2021 15:54:08 +0100 [thread overview]
Message-ID: <163456884845.2614702.5758884460753061615.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <163456861570.2614702.14754548462706508617.stgit@warthog.procyon.org.uk>
Remove a bunch of now-unused fscache stats counters that were obsoleted by
the removal of the old I/O routines.
Signed-off-by: David Howells <dhowells@redhat.com>
