      Commit 4580a92d "NFS: Use server-recommended security flavor by
      default (NFSv3)" introduced a behavior regression for NFS mounts
      done via a legacy binary mount(2) call.
      
      Ensure that a default security flavor is specified for legacy binary
      mount requests, since they do not invoke nfs_select_flavor() in the
      kernel.
      
      Busybox uses klibc's nfsmount command, which performs NFS mounts
      using the legacy binary mount data format.  /sbin/mount.nfs is not
      affected by this regression.

      SUNRPC: Prevent an rpc_task wakeup race · a3c3cac5
      Trond Myklebust authored
      The lockless RPC_IS_QUEUED() test in __rpc_execute means that we need to
      be careful about ordering the calls to rpc_test_and_set_running(task) and
      rpc_clear_queued(task). If we get the order wrong, then we may end up
      testing the RPC_TASK_RUNNING flag after __rpc_execute() has looped
      and changed the state of the rpc_task.

      NFSv4.1 Fix a pNFS session draining deadlock · 774d5f14
      Andy Adamson authored
      On a CB_RECALL the callback service thread flushes the inode using
      filemap_flush prior to scheduling the state manager thread to return the
      delegation. When pNFS is used and I/O has not yet gone to the data server
      servicing the inode, a LAYOUTGET can preceed the I/O. Unlike the async
      filemap_flush call, the LAYOUTGET must proceed to completion.
      
      If the state manager starts to recover data while the inode flush is sending
      the LAYOUTGET, a deadlock occurs as the callback service thread holds the
      single callback session slot until the flushing is done which blocks the state
      manager thread, and the state manager thread has set the session draining bit
      which puts the inode flush LAYOUTGET RPC to sleep on the forechannel slot
      table waitq.
      
      Separate the draining of the back channel from the draining of the fore channel
      by moving the NFS4_SESSION_DRAINING bit from session scope into the fore
      and back slot tables.  Drain the back channel first allowing the LAYOUTGET
      call to proceed (and fail) so the callback service thread frees the callback
      slot. Then proceed with draining the forechannel.

      Pull tracing/kprobes update from Steven Rostedt:
       "The majority of these changes are from Masami Hiramatsu bringing
        kprobes up to par with the latest changes to ftrace (multi buffering
        and the new function probes).
      
        He also discovered and fixed some bugs in doing so.  When pulling in
        his patches, I also found a few minor bugs as well and fixed them.
      
        This also includes a compile fix for some archs that select the ring
        buffer but not tracing.
      
        I based this off of the last patch you took from me that fixed the
        merge conflict error, as that was the commit that had all the changes
        I needed for this set of changes."
