    Pull io_uring updates from Jens Axboe:
     "Here are the io_uring updates queued up for 6.11.
    
      Nothing major this time around, various minor improvements and
      cleanups/fixes. This contains:
    
       - Add bind/listen opcodes. Main motivation is to support direct
         descriptors, to avoid needing a regular fd just for doing these two
         operations (Gabriel)
    
       - Probe fixes (Gabriel)
    
       - Treat io-wq work flags as atomics. Not fixing a real issue, but may
         as well and it silences a KCSAN warning (me)
    
       - Cleanup of rsrc __set_current_state() usage (me)
    
       - Add 64-bit for {m,f}advise operations (me)
    
       - Improve performance of data ring messages (me)
    
       - Fix for ring message overflow posting (Pavel)
    
       - Fix for freezer interaction with TWA_NOTIFY_SIGNAL. Not strictly an
         io_uring thing, but since TWA_NOTIFY_SIGNAL was originally added
         for faster task_work signaling for io_uring, bundling it with this
         pull (Pavel)
    
       - Add Pavel as a co-maintainer
    
       - Various cleanups (me, Thorsten)"
