--- Comment #7 from Serhei Makarov <me at serhei dot io> ---
It appears that the recent kernels introduces some timing issue between kernel-
and user-space map operations. Filing as stapbpf pr24659
Changing the second probe vfs_read to probe timer.s(2) would make the testcase
pass on new kernels as well as old ones. But let's keep next.stp as-is and use
it to test for pr24659 as well.
