From: Xiong Zhou <jencce.kernel@xxxxxxxxx>
In jbd{2}.h, BH_PrivateStart is used in the define of enum jbd_state_bits,
which is defined in buffer_head.h under ifdef CONFIG_BLOCK. In these
two headers, BUFFER_FNS and TAS_BUFFER_FNS and jbd_common.h refer to
enum jbd_state_bits, so they should under ifdef CONFIG_BLOCK.
