Yucong Sun	d3f7b1664d	selfetest/bpf: Make some tests serial ... Change tests that often fails in parallel execution mode to serial.

Yucong Sun	a6258837c8	selftests/bpf: Reduce flakyness in timer_mim ... This patch extends wait time in timer_mim. As observed in slow CI environment, it is possible to have interrupt/preemption long enough to cause the test to fail, almost 1 failure in 5 runs.

Alexei Starovoitov	61f71e746c	selftests/bpf: Add a test with bpf_timer in inner map. ... Check that map-in-map supports bpf timers. Check that indirect "recursion" of timer callbacks works: timer_cb1() { bpf_timer_set_callback(timer_cb2); } timer_cb2() { bpf_timer_set_callback(timer_cb1); } Check that bpf_map_release htab_free_prealloced_timers bpf_timer_cancel_and_free hrtimer_cancel works while timer cb is running. "while true; do ./test_progs -t timer_mim; done" is a great stress test. It caught missing timer cancel in htab->extra_elems. timer_mim_reject.c is a negative test that checks that timer<->map mismatch is prevented.
