Pull io_uring fixes from Jens Axboe:

 - Series fixing an issue with multishot read on pollable files that may
   return -EIOCBQUEUED from ->read_iter(). Four 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
