commit ec0dd267bf7d08cb30e321e45a75fd40edd7e528

    SUNRPC: Fix use of static variable in rpcb_getport_async
    
    Because struct rpcbind_args *map was declared static, if two
    threads entered this method at the same time, the values
    assigned to map could be sent two two differen tasks.
    This could cause all sorts of problems, include use-after-free
    and double-free of memory.
    
    Fix this by removing the static declaration so that the map
    pointer is on the stack.

    SUNRPC: Fix a race between work-queue and rpc_killall_tasks
    
    Since rpc_killall_tasks may modify the rpc_task's tk_action field
    without any locking, we need to be careful when dereferencing it.

commit 2bea038c52e88badbbd5b420c1de918f7f2579e9
Author: Boaz Harrosh <bharrosh@panasas.com>

    pnfs: write: Set mds_offset in the generic layer - it is needed by all LDs
    
    In current pnfs tree, all the layouts set mds_offset in their
    .write_pagelist member.
    mds_offset is only used by generic layer and should be handled by it.
    
    This patch is for upstream. It is needed in this -rc series to fix a
    bug in objects layout_commit.
    
    I'll send patches for objects and blocks to be
    squashed into current pnfs tree.
    
    TODO: It looks like the read path needs the same patch.
