Hi all,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

(and many more)

Introduced by commit

  7caa47151ab2 ("blkcg: implement blk-iocost")

To get these warnings you need to build with CONFIG_HEADER_TEST and
CONFIG_KERNEL_HEADER_TEST (and maybe CONFIG_UAPI_HEADER_TEST).
allmodconfig does that.
