From 044deda3cd9f2df3e3a9df3c8b74d5b82e7ae6e6 Mon Sep 17 00:00:00 2001 From: Steve French Date: Fri, 21 Nov 2008 14:22:57 +0530 Subject: [PATCH] cifs: remove unused list, add new cifs sock list to prepare for mount/umount fix commit fb396016647ae9de5b3bd8c4ee4f7b9cc7148bd5 upstream. Also adds two lines missing from the previous patch (for the need reconnect flag in the /proc/fs/cifs/DebugData handling) The new global_cifs_sock_list is added, and initialized in init_cifs but not used yet. Jeff Layton will be adding code in to use that and to remove the GlobalTcon and GlobalSMBSession lists.
