[linux-cifs-client] oplock problem with files from multiple clients

[Steve French]

Just fixed an oplock problem that could cause in some cases a cifs vfs
client to read stale data when the file is multiply open and later
updated on the server.  This is in the 1.0.2 version of the cifs vfs
code in the cifs vfs 2.6 development bk tree.  Will check the 2.4
version into Samba CVS and post patches tomorrow.
