Hi Jens,

After merging the block tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

block/kyber-iosched.c:84:22: warning: integer overflow in expression of type 'long int' results in '705032704' [-Woverflow]
  [KYBER_DISCARD] = 5 * NSEC_PER_SEC,
                      ^

Introduced by commit

  6e25cb01ea20 ("kyber: implement improved heuristics")
