The vmlinux selftest triggers nanosleep and checks that both kprobe and fentry programs observe the hrtimer enqueue path. After the hrtimer_start_expires_user() conversion [1], nanosleep reaches hrtimer_start_range_ns_user() instead of hrtimer_start_range_ns(). Hard-coding either symbol makes the test fail either on bpf tree or on linux-next [2]. Keep both hook variants as optional BPF programs and enable the pair matching the running kernel before loading the object. This is also a nice example of how to modify a BPF program to work on both older and newer kernel revision.
