| |
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>
With security updates, %p in the kernel is hashed to protect true kernel locations. But trace_printk() is not allowed in production systems, and when a pointer is used, there are many times that the actual address is needed. "%px" produces the real address. But libtraceevent does not know how to handle that extension. Add it.
