Subject: [PATCH] tools/mdflush: include blkdev.h instead of genhd.h

In recent kernels, i.e. since commit 322cbb50de71 ("block: remove

genhd.h"), genhd.h header has been removed and its content moved to

blkdev.h. Since genhd.h has been included in blkdev.h since forever,

including blkdev instead of genhd in the mdflush tool works for both

older and newer kernel.
