Hi Muhammad,
In case you're interested in going slightly deeper on this:
Entertainingly, there are several kselftest dirs that also use this attribute directly, and I quite enjoyed seeing that the *same* attribute is now defined as:
__maybe_unused __always_unused __unused # from your patch here
$ git grep -n '__attribute__((__unused__))' bpf/prog_tests/sockmap_helpers.h:11:#define __always_unused __attribute__((__unused__)) landlock/audit.h:28:#define __maybe_unused __attribute__((__unused__)) landlock/common.h:26:#define __maybe_unused __attribute__((__unused__)) mm/pkey-helpers.h:88:# define __maybe_unused __attribute__((__unused__)) mm/protection_keys.c:1307: __attribute__((__unused__)) int peek_result; net/ovpn/ovpn-cli.c:37:#define __always_unused __attribute__((__unused__)) perf_events/watermark_signal.c:20:#define __maybe_unused __attribute__((__unused__))
thanks,
