Pull btrfs fixes from David Sterba:
 "A few more fixes.

  Besides the one-liners in Btrfs there's fix to the io_uring and
  encoded read integration (added in this development cycle). The update
  to io_uring provides more space for the ongoing command that is then
  used in Btrfs to handle some cases.

   - io_uring and encoded read:
       - provide stable storage for io_uring command data
       - make a copy of encoded read ioctl call, reuse that in case the
         call would block and will be called again

   - properly initialize zlib context for hardware compression on s390

   - fix max extent size calculation on filesystems with non-zoned
     devices

   - fix crash in scrub on crafted image due to invalid extent tree"
