+Subject: [PATCH] perf probe: Add missing libgen.h header needed for using
+ basename()
+
+This prototype is obtained indirectly, by luck, from some other header
+in probe-event.c in most systems, but recently exploded on alpine:edge:
+
+   8    13.39 alpine:edge                   : FAIL gcc version 13.2.1 20240309 (Alpine 13.2.1_git20240309)
+    util/probe-event.c: In function 'convert_exec_to_group':
+    util/probe-event.c:225:16: error: implicit declaration of function 'basename' [-Werror=implicit-function-declaration]
+      225 |         ptr1 = basename(exec_copy);
+          |                ^~~~~~~~
+    util/probe-event.c:225:14: error: assignment to 'char *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
+      225 |         ptr1 = basename(exec_copy);
+          |              ^
+    cc1: all warnings being treated as errors
+    make[3]: *** [/git/perf-6.8.0/tools/build/Makefile.build:158: util] Error 2
+
+Fix it by adding the libgen.h header where basename() is prototyped.

+Subject: [PATCH] bpftool: Be more portable by using POSIX's basename()
+
+musl libc had the basename() prototype in string.h, but this is a
+glibc-ism, now they removed the _GNU_SOURCE bits in their devel distro,
+Alpine Linux edge:
+
+  https://git.musl-libc.org/cgit/musl/commit/?id=725e17ed6dff4d0cd22487bb64470881e86a92e7
+
+So lets use the POSIX version, the whole rationale is spelled out at:
