Added bpf_{updata,delete}_map_elem to the very map element the iter program is visiting. Due to rcu protection, the visited map elements, although stale, should still contain correct values. $ ./test_progs -n 4/18 #4/18 bpf_hash_map:OK #4 bpf_iter:OK Summary: 1/1 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by:
