or directory
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Focal:
Fix Committed
Bug description:
Please partially revert:
[focal] d946d4ddd6af bpf: Zero-fill re-used per-cpu map element
Such that we drop the tools/testing/selftests change but keep the beneficial
change to kernel/bpf/hashtab.c.
Reported upstream:

This v5.4.78 commit breaks the tools/testing/selftests/bpf build:
[linux-5.4.y] c602ad2b52dc bpf: Zero-fill re-used per-cpu map element
[focal] d946d4ddd6af bpf: Zero-fill re-used per-cpu map element
Like this:
prog_tests/map_init.c:5:10: fatal error: test_map_init.skel.h: No
such file or directory
5 | #include "test_map_init.skel.h"
Because tools/testing/selftests/bpf/Makefile in v5.4 does not have the
"skeleton header generation" stuff (circa v5.6).
