Subject: [for-next][PATCH 2/6] doc: trace: Fix documentation for uprobe_profile
Date: Tue, 05 Mar 2019 08:52:25 -0500 [thread overview]
Message-ID: <20190305135245.954711317@goodmis.org> (raw)
In-Reply-To: <20190305135223.360347148@goodmis.org>
From: Srikar Dronamraju <srikar@linux.vnet.ibm.com>
uprobe_profile has filename and number of probe hits information for
each uprobe event. The documentation erroneously talks about probe
mis-hits. Update the documentation to the correct information.
