From fca5238ef3232cd0cf4bf0457e751b3bb20912a9 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Fri, 24 Dec 2010 01:32:32 +0000 Subject: [PATCH] NFS: Allow walking nfs_client.cl_superblocks list outside client.c We're about to move some fields from struct nfs_client to struct nfs_server. There is a many-to-one relationship between nfs_servers and nfs_clients. After these fields are moved to the nfs_server struct, to visit all of the data in these fields that is owned by one nfs_client, code will need to visit each nfs_server on the cl_superblocks list for that nfs_client. To serialize changes to the cl_superblocks list during these little expeditions, protect the list with RCU.
