Merge tag 'io_uring-6.9-20240322' of git://git.kernel.dk/linux

Pull more io_uring updates from Jens Axboe:
 "One patch just missed the initial pull, the rest are either fixes or
  small cleanups that make our life easier for the next kernel:

   - Fix a potential leak in error handling of pinned pages, and clean
     it up (Gabriel, Pavel)

   - Fix an issue with how read multishot returns retry (me)

   - Fix a problem with waitid/futex removals, if we hit the case of
     needing to remove all of them at exit time (me)

   - Fix for a regression introduced in this merge window, where we
     don't always have sr->done_io initialized if the ->prep_async()
     path is used (me)

   - Fix for SQPOLL setup error handling (me)

   - Fix for a poll removal request being delayed (Pavel)

   - Rename of a struct member which had a confusing name (Pavel)"
