This reverts commit bed9e27baf52a09b7ba2a3714f1e24e17ced386d. The original set [1][2] was expected to undo a suboptimal fix in [2], and replace it with a better fix [1]. However, as reported by Dan Moulding [2] causes an issue with raid5 with journal device. Revert [2] for now to close the issue. We will follow up on another issue reported by Juxiao Bi, as [2] is expected to fix it. We believe this is a good trade-off, because the latter issue happens less freqently. In the meanwhile, we will NOT revert [1], as it contains the right logic.
