From f29c50419c8d1998edd759f1990c4243a248f469 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 19 May 2011 14:35:33 -0400 Subject: maccess,probe_kernel: Make write/read src const void * The functions probe_kernel_write() and probe_kernel_read() do not modify the src pointer. Allow const pointers to be passed in without the need of a typecast.
