Hi NeilBrown,

FYI, kernel build failed on

tree:   git://neil.brown.name/md for-next/14817e9
head:   14817e9a6dab027db44783d28429d14f601547a2
commit: 14817e9a6dab027db44783d28429d14f601547a2 [29/29] md/raid5: add blktrace calls
config: sparc64-defconfig

ERROR: "__tracepoint_block_unplug" [drivers/md/raid456.ko] undefined!

The root cause is, the block trace points are only available when
block/blk-core.c is compiled in.
