From: Martin Wilck <mwilck@xxxxxxxx>
Hi Christophe, hi Ben, hi lixiaokeng,
this series was inspired by lixiaokeng's recent posting "[QUESTION] memory
leak in main (multipath)". It implements my first idea, registering
cleanup handlers with atexit(). However it turned out to be quite
complex. In particular multipathd has a lot of things to clean up.
This series is based on the previous series "multipath-tools: shutdown,
libdevmapper races, globals".
While the bulk of the series is the cleanup handling, it also contains
some bug fixes for issues that I found while working on this.
Regards
Martin
