Merge tag 'xfs-fixes-6.17-rc4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Carlos Maiolino:
 "The highlight I'd like to point here is related to the XFS_RT
  Kconfig, which has been updated to be enabled by default now if
  CONFIG_BLK_DEV_ZONED is enabled.

  This also contains a few fixes for zoned devices support in XFS,
  specially related to swapon requests in inodes belonging to the zoned
  FS.

  A null-ptr dereference fix in the xattr data, due to a mishandling of
  medium errors generated by block devices is also included"

* tag 'xfs-fixes-6.17-rc4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
  xfs: do not propagate ENODATA disk errors into xattr code
  xfs: reject swapon for inodes on a zoned file system earlier
  xfs: kick off inodegc when failing to reserve zoned blocks
  xfs: remove xfs_last_used_zone
  xfs: Default XFS_RT to Y if CONFIG_BLK_DEV_ZONED is enabled
