Subject: [GIT PULL] Btrfs fixes for 6.13-rc7

Hi,

please pull 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.

Please pull, thanks.

- 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
