Subject: [PATCH v2 05/26] NFS: Fix up revalidation of space used
Date: Wed, 14 Apr 2021 09:43:32 -0400 [thread overview]
Message-ID: <20210414134353.11860-6-trondmy@kernel.org> (raw)
In-Reply-To: <20210414134353.11860-5-trondmy@kernel.org>
From: Trond Myklebust <trond.myklebust@hammerspace.com>
Ensure that when the change attribute or the size change, we also
remember to revalidate the space used.
