Andrii Nakryiko e1aa01195b bpf: Fix map leak in HASH_OF_MAPS map ... [ Upstream commit 1d4e1eab45 ] Fix HASH_OF_MAPS bug of not putting inner map pointer on bpf_map_elem_update() operation. This is due to per-cpu extra_elems optimization, which bypassed free_htab_elem() logic doing proper clean ups. Make sure that inner map is put properly in optimized case as well.
