[ewg] [GIT PULL OFED-1.5] NFSRDMA bug fixes

[Jon Mason]

Hey Vlad,

Please pull from

ssh://vlad@sofa.openfabrics.org/home/jon/scm/ofed_kernel-1.5.git dev

It contains the following patches (notice that the RHEL5.4 patch is in this):

commit c69ce7cc166127b8011b8e10706520e396f87362
Author: Jon Mason <jon at opengridcomputing.com>
Date:   Fri Jul 10 15:35:07 2009 -0500

    kref safety checks were removed in previous versions due to kref
    behaving differently in 2.6.18 (and older).  These sanity checks are
    needed for IB (though never hit on iWARP testing).  This patch re-adds
    them and updates them with the correct behavior.
    
    This fixes RHEL5.4.

    The proc entries in net/sunrpc/xprtrdma/svc_rdma.c need a ctl_name,
    otherwise they will not be included in /proc.
    
    This fixes SLES10sp2

    Add RHEL5.4 support with NFSRDMA backport.
    
    This is mostly a copy of the RHEL5.3 tree with updated OFED scripts.
    With this patch, I am able to build the NFS module (and the NFS module
    only) without issue and it passes Connectahon over TCP.

Let me know if you want me to remove the RHEL5.4 patch and resubmit this seperately.

Thanks,
Jon
