From 321eceda5c5f80df06a75260da3df2caf37ad55d Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Mon, 10 Dec 2018 13:45:22 -0500 Subject: [PATCH] tools lib traceevent: Fix processing of dereferenced args in bprintk events commit f024cf085c423bac7512479f45c34ee9a24af7ce upstream. In the case that a bprintk event has a dereferenced pointer that is stored as a string, and there's more values to process (more args), the arg was not updated to point to the next arg after processing the dereferenced pointer, and it screwed up what was to be displayed.
