Subject: [PATCH 7/7] kernel-trace: Delete an error message for a failed memory allocation in create_trace_uprobe()
Date: Fri, 5 May 2017 23:10:51 +0200 [thread overview]
Message-ID: <74587923-6261-8177-bff3-57cff57b8e87@users.sourceforge.net> (raw)

The script "checkpatch.pl" pointed information out like the following.
WARNING: Possible unnecessary 'out of memory' message
Thus remove such a statement here.
