Subject: [PATCH 1/8] kernel-shark: Don't free the string field of KS_CONFIG_STRING document
Date: Tue,  9 Jul 2019 18:56:43 +0300	[thread overview]
Message-ID: <20190709155650.2345-2-y.karadz@gmail.com> (raw)
In-Reply-To: <20190709155650.2345-1-y.karadz@gmail.com>

In kshark_config_doc_get() if the outputted document is of type
KS_CONFIG_STRING, do not try to free the old string before setting
the new one. Note that those strings are owned by the json object.

Reported-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
Fixes: 	b3b5b6504b1 ("kernel-shark-qt: Add I/O for configuration data.")
