Subject: [PATCH 06/14] NFS: Rename nfs_inode_return_delegation_noreclaim()
Date: Wed, 23 Oct 2019 19:55:52 -0400 [thread overview]
Message-ID: <20191023235600.10880-7-trond.myklebust@hammerspace.com> (raw)
In-Reply-To: <20191023235600.10880-6-trond.myklebust@hammerspace.com>
Rename nfs_inode_return_delegation_noreclaim() to
nfs_inode_evict_delegation(), which better describes what it
does.
