      floppy: destroy floppy workqueue before cleaning up the queue · eac7cc52

      We need to first destroy the floppy_wq workqueue before cleaning up
      the queue. Otherwise we might race with still pending work with the
      workqueue, but all the block queue already gone. This might lead to
      various oopses, such as

      Pull NFS client bugfixes from Trond Myklebust:
      
       - Fix a bunch of deadlock situations:
         * State recovery can deadlock if we fail to release sequence ids
           before scheduling the recovery thread.
         * Calling deactivate_super() from an RPC workqueue thread can
           deadlock because of the call to rpc_shutdown_client.
      
       - Display the device name correctly in /proc/*/mounts
      
       - Fix a number of incorrect error return values:
         * When NFSv3 mounts fail due to a timeout.
         * On NFSv4.1 backchannel setup failure
         * On NFSv4 open access checks
      
       - pnfs_find_alloc_layout() must check the layout pointer for NULL
      
       - Fix a regression in the legacy DNS resolved
      
      * tag 'nfs-for-3.7-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs:
        NFS4: nfs4_opendata_access should return errno
        NFSv4: Initialise the NFSv4.1 slot table highest_used_slotid correctly
        SUNRPC: return proper errno from backchannel_rqst
        NFS: add nfs_sb_deactive_async to avoid deadlock
        nfs: Show original device name verbatim in /proc/*/mount{s,info}
        nfsv3: Make v3 mounts fail with ETIMEDOUTs instead EIO on mountd timeouts
        nfs: Check whether a layout pointer is NULL before free it
        NFS: fix bug in legacy DNS resolver.
        NFSv4: nfs4_locku_done must release the sequence id
        NFSv4.1: We must release the sequence id when we fail to get a session slot
        NFS: Wait for session recovery to finish before returning

      Pull i2c embedded fixes from Wolfram Sang:
       "Two patches are usual stuff.
      
        The bigger patch is needed to correct a wrong decision made in this
        merge window.  We hoped to get the PIOQUEUE mode in the mxs driver
        working with DMA, but it turned out to be too broken (leading to data
        loss), so we now think it is best to remove it entirely and work only
        with DMA now.  The patch should be in 3.7.  IMO, so users never get
        the chance to use both modes in parallel."
