Timing of the change aside, this patch doesn't even apply to the 4.15
block tree:

checking file block/blk-core.c
checking file include/linux/writeback.h
Hunk #1 succeeded at 309 (offset -20 lines).
checking file mm/page-writeback.c
Hunk #1 FAILED at 1977.
Hunk #2 FAILED at 1988.
2 out of 2 hunks FAILED
