#     Merge tag 'for-4.20-rc5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fix from David Sterba:
#      "A patch in 4.19 introduced a sanity check that was too strict and a
#       filesystem cannot be mounted.
#     
#       This happens for filesystems with more than 10 devices and has been
#       reported by a few users so we need the fix to propagate to stable"
#
