Merge tag 'for-6.19-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave...

Pull btrfs fixes from David Sterba:

 - protect reading super block vs setting block size externally (found
   by syzbot)

 - make sure no transaction is started in read-only mode even with some
   rescue mount option combinations

 - fix checksum calculation of backup super blocks when block-group-tree
   is enabled

 - more extensive mount-time checks of device items that could be left
   after device replace and attempting degraded mount

 - fix build warning with -Wmaybe-uninitialized on loongarch64-gcc 12
