      io_uring: short circuit -EAGAIN for blocking read attempt · f91daf56
      Jens Axboe authored
      One case was missed in the short IO retry handling, and that's hitting
      -EAGAIN on a blocking attempt read (eg from io-wq context). This is a
      problem on sockets that are marked as non-blocking when created, they
      don't carry any REQ_F_NOWAIT information to help us terminate them
      instead of perpetually retrying.
      
      Fixes: 227c0c96 ("io_uring: internally retry short reads")

      io_uring: sanitize double poll handling · d4e7cd36
      Jens Axboe authored
      There's a bit of confusion on the matching pairs of poll vs double poll,
      depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
      poll driven retry.
      
      Add io_poll_get_double() that returns the double poll waitqueue, if any,
      and io_poll_get_single() that returns the original poll waitqueue. With
      that, remove the argument to io_poll_remove_double().
      
      Finally ensure that wait->private is cleared once the double poll handler
      has run, so that remove knows it's already been seen.

       "Fixes:
         - Fixes for 'perf bench numa'.

         - 'perf ftrace' improvements to provide similar options for this
           utility so that one can go from 'perf record', 'perf trace', etc to
           'perf ftrace' just by changing the name of the subcommand.
      
         - Prefer new "sched:sched_waking" trace event when it exists in 'perf
           sched' post processing.
      
         - Update POWER9 metrics to utilize other metrics.
      
         - Fall back to querying debuginfod if debuginfo not found locally.
