This patch introduces {set|clear}_wb_congested() and wb_congested() which take a bdi_writeback_congested and bdi_writeback respectively. The bdi counteparts are now wrappers invoking the wb based functions on @bdi->wb. While converting clear_bdi_congested() to clear_wb_congested(), the local variable declaration order between @wqh and @bit is swapped for cosmetic reason. This patch just adds the new wb based functions. The following patches will apply them. v2: Updated for bdi_writeback_congested.
