Subject: [PATCH] trace-cmd: fix writing of uncompressed size
Date: Mon, 11 Jul 2022 09:44:18 +0200	[thread overview]
Message-ID: <20220711074418.858843-1-svens@linux.ibm.com> (raw)

Pass &size instead of &handle->pointer. Interestingly this doesn't hurt
on x86, but makes trace-cmd fail on s390.

Fixes: 3f8447b1 ("trace-cmd library: Add support for compression algorithms")
Signed-off-by: Sven Schnelle <svens@linux.ibm.com>
