ftrace: disable tracing on resize
Impact: fix for bug on resize This patch addresses the bug found here: http://bugzilla.kernel.org/show_bug.cgi?id=11996 When ftrace converted to the new unified trace buffer, the resizing of the buffer was not protected as much as it was originally. If tracing is performed while the resize occurs, then the buffer can be corrupted. This patch disables all ftrace buffer modifications before a resize takes place.
