      io_uring: fix error handling in io_queue_link_head · 2e6e1fde
      Pavel Begunkov authored
      In case of an error io_submit_sqe() drops a request and continues
      without it, even if the request was a part of a link. Not only it
      doesn't cancel links, but also may execute wrong sequence of actions.
      
      Stop consuming sqes, and let the user handle errors.

      io_uring: use hash table for poll command lookups · 78076bb6
      Jens Axboe authored
      We recently changed this from a single list to an rbtree, but for some
      real life workloads, the rbtree slows down the submission/insertion
      case enough so that it's the top cycle consumer on the io_uring side.
      In testing, using a hash table is a more well rounded compromise. It
      is fast for insertion, and as long as it's sized appropriately, it
      works well for the cancellation case as well. Running TAO with a lot
      of network sockets, this removes io_poll_req_insert() from spending
      2% of the CPU cycles.

      io-wq: clear node->next on list deletion · 08bdcc35
      Jens Axboe authored
      If someone removes a node from a list, and then later adds it back to
      a list, we can have invalid data in ->next. This can cause all sorts
      of issues. One such use case is the IORING_OP_POLL_ADD command, which
      will do just that if we race and get woken twice without any pending
      events. This is a pretty rare case, but can happen under extreme loads.
      Dan reports that he saw the following crash:

      which is caused by slab fault injection triggering a failure in
      prepare_creds(). We don't actually need to create a copy of the creds
      as we're not modifying it, we just need a reference on the current task
      creds. This avoids the failure case as well, and propagates the const
      throughout the stack.

      Pull i2c updates from Wolfram Sang:
       "I2C has mostly driver updates this time.
      
        The few noteworthy changes are: the core has now support for analog
        and digital filters with at91 being the first user, a core addition to
        replace the NULL returning i2c_new_probed_device() with an ERR_PTR
        variant, and the pxa driver has finally being moved to use the generic
        I2C slave interface. We have quite a significant number of reviews per
        patch this time, so thank you to all involved!"

         - Add highmem.h include for io_uring, because of the kmap() additions
           from last round. For some reason the build bot didn't spot this
           even though it sat for days.
