Martin KaFai Lau 387b532138 selftests/bpf: Tracing prog can still do lookup under busy lock ... This patch modifies the task_ls_recursion test to check that the first bpf_task_storage_get(&map_a, ...) in BPF_PROG(on_update) can still do the lockless lookup even it cannot acquire the percpu busy lock. If the lookup succeeds, it will increment the value by 1 and the value in the task storage map_a will become 200+1=201. After that, BPF_PROG(on_update) tries to delete from map_a and should get -EBUSY because it cannot acquire the percpu busy lock after finding the data.
