[PATCH 02/11] dynamic_debug: trim source-path prefix from dynamic_debug/control

From: Jim Cromie
Date: Tue Jun 28 2011 - 03:15:00 EST


Skip past unchanging absolute source-path prefix to print a path
thats relative to kernel source's root-dir. This makes the file
easier to read without a wide screen. For example:

kernel/freezer.c:128 [freezer]cancel_freezing - " clean up: %s\012"
