Subject: [PATCH 07/12] fscache: Remove the object list procfile
Date: Mon, 21 Jun 2021 22:46:23 +0100	[thread overview]
Message-ID: <162431198332.2908479.5847286163455099669.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <162431188431.2908479.14031376932042135080.stgit@warthog.procyon.org.uk>

Remove the object list procfile from fscache as objects will become
entirely internal to the cache.

Signed-off-by: David Howells <dhowells@redhat.com>
