Subject: [dm-devel] [PATCH v2 23/29] multipath-tools: mpath-tools.supp: file with valgrind suppressions
Date: Fri, 16 Oct 2020 12:44:55 +0200	[thread overview]
Message-ID: <20201016104501.8700-24-mwilck@suse.com> (raw)
In-Reply-To: <20201016104501.8700-1-mwilck@suse.com>

From: Martin Wilck <mwilck@suse.com>

These leaks are caused by other libraries (libsystemd, glibc,
libgcrypt) and should be ignored when debugging with valgrind

Usage example:

valgrind --suppressions=mpath-tools.supp \
    --leak-check=full --show-leak-kinds=all $COMMAND
