Hi Linus,

Some fixes for io_uring that should go into the 6.14 kernel release.
This pull request contains:

- Series fixing an issue with multishot read on pollable files that may
  return -EIOCBQUEUED from ->read_iter(). 4 small patches for that, the
  first one deliberately done in such a way that it'd be easy to
  backport.

- Remove some dead constant definitions.

- Use array_index_nospec() for opcode indexing.

- Work-around for worker creation retries in the presence of signals.

Please pull!
