-Subject: [PATCH] Drop on_exit(), use standard atexit() instead
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-`on_exit()` is a GLIBC specific extension and not available in musl and uClibc.
-
-Portable applications should avoid this function, and use the standard
-`atexit()` instead.
-
-Backported from:f6e20c9c6e9b50963caaf5483248d329473a6815
