Subject: [PATCH v2 11/26] NFS: Don't set NFS_INO_REVAL_PAGECACHE in the inode cache validity
Date: Wed, 14 Apr 2021 09:43:38 -0400
Message-ID: <20210414134353.11860-12-trondmy@kernel.org> (raw)
In-Reply-To: <20210414134353.11860-11-trondmy@kernel.org>

From: Trond Myklebust <trond.myklebust@hammerspace.com>

It is no longer necessary to preserve the NFS_INO_REVAL_PAGECACHE flag.
