Subject: [PATCH 4/4] NFS: Move cl_delegations to the nfs_server struct
Date: Thu, 23 Dec 2010 20:33:04 -0500 [thread overview]
Message-ID: <20101224013304.2445.53552.stgit@matisse.1015granger.net> (raw)
In-Reply-To: <20101224012636.2445.41411.stgit@matisse.1015granger.net>
Delegations are per-inode, not per-nfs_client. When a server file
system is migrated, delegations on the client must be moved from the
source to the destination nfs_server. Make it easier to manage a
mount point's delegation list across a migration event by moving the
list to the nfs_server struct.
Clean up: I added documenting comments to public functions I changed
in this patch. For consistency I added comments to all the other
public functions in fs/nfs/delegation.c.
