Hi Linus,

Wasn't expecting this to be so big, and if I was, I would have used
separate branches for this. Going forward I'll be doing separate
branches for the current tree, just like for the next kernel version
tree. In any case, this pull request contains:

- Series from Christoph that fixes an inherent race condition with zoned
  devices and revalidation.

- null_blk zone size fix (Damien)

- Fix for a regression in this merge window that caused busy spins by
  sending empty disk uevents (Eric)

- Fix for a regression in this merge window for bfq stats (Hou)

- Fix for io_uring creds allocation failure handling (me)

- io_uring -ERESTARTSYS send/recvmsg fix (me)

- Series that fixes the need for applications to retain state across
  async request punts for io_uring. This one is a bit larger than I
  would have hoped, but I think it's important we get this fixed for
  5.5.

- connect(2) improvement for io_uring, handling EINPROGRESS instead of
  having applications needing to poll for it (me)

- Have io_uring use a hash for poll requests instead of an rbtree. This
  turned out to work much better in practice, so I think we should make
  the switch now. For some workloads, even with a fair amount of
  cancellations, the insertion sort is just too expensive. (me)

- Various little io_uring fixes (me, Jackie, Pavel, LimingWu)

- Fix for brd unaligned IO, and a warning for the future (Ming)

- Fix for a bio integrity data leak (Justin)

- bvec_iter_advance() improvement (Pavel)

- Xen blkback page unmap fix (SeongJae)

The major items in here are all well tested, and on the liburing side we
continue to add regression and feature test cases. We're up to 50 topic
cases now, each with anywhere from 1 to more than 10 cases in each.

Please pull!
