Subject: [PATCH v2 4/5] NFS: Fix open coded versions of nfs_set_cache_invalid()
Date: Mon,  8 Mar 2021 14:42:54 -0500	[thread overview]
Message-ID: <20210308194255.7873-4-trondmy@kernel.org> (raw)
In-Reply-To: <20210308194255.7873-3-trondmy@kernel.org>

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

nfs_set_cache_invalid() has code to handle delegations, and other
optimisations, so let's use it when appropriate.
