 client

Hi Linus,

Please pull from the "bugfixes" branch of the repository at

   git pull git://git.linux-nfs.org/projects/trondmy/nfs-2.6.git bugfixes

This will update the following files through the appended changesets.

These patches mainly fix issues with the NFSv4.1 session and state recovery code.

  Cheers,
    Trond

commit 72211dbe727f7c1451aa5adfcbd1197b090eb276
Author: Trond Myklebust <Trond.Myklebust@...app.com>

    NFSv4: Release the sequence id before restarting a CLOSE rpc call
    
    If the CLOSE or OPEN_DOWNGRADE call triggers a state recovery, and has
    to be resent, then we must release the seqid. Otherwise the open
    recovery will wait for the close to finish, which causes a deadlock.
    
    This is mainly a NFSv4.1 problem, although it can theoretically happen
    with NFSv4.0 too, in a OPEN_DOWNGRADE situation.

    nfs41: fix session fore channel negotiation
    
    If the rsize or wsize is not set on the mount command, negotiate the highest
    supported rsize and wsize in session creation.
    
    Fixes a bug where the client negotiated nfs41_maxwrite_overhead as
    ca_maxrequestsize and nfs41_maxread_overhead as ca_maxresponsesize resulting
    in NFS4ERR_REQ_TOO_BIG errors on writes.
