Hi Linus,

Here's a set of changes/fixes that should go into 5.5-rc. This pull
request contains:

- A tweak to IOSQE_IO_LINK (also marked for stable) to allow links that
  don't sever if the result is < 0. This is mostly for linked timeouts,
  where if we ask for a pure timeout we always get -ETIME. This makes
  links useless for that case, hence allow a case where it works.

- Five minor optimizations to fix and improve cases that regressed
  since v5.4.

- An SQTHREAD locking fix.

- A sendmsg/recvmsg iov assignment fix.

- Net fix where read_iter/write_iter don't honor IOCB_NOWAIT, and
  subsequently ensuring that works for io_uring.

- Fix a case where for an invalid opcode we might return -EBADF instead
  of -EINVAL, if the ->fd of that sqe was set to an invalid fd value.

Please pull!
