Log:
MFC r331420 (by avg): zfs: fix mismatch between format specifier and type
vdev_dbgmsg_print_tree printed vdev_id of uint64_t type with %u format
specifier. That caused subsequent parameters to be incorrectly read
from the stack and lead to a crash when a wrong value was interpreted as
a string pointer.
This should be upstreamed.
