Kprobes: Make kprobe.symbol_name const
Ananth N Mavinakayanahalli [Tue, 8 May 2007 07:26:23 +0000 (00:26 -0700)]
Kprobes doesn't scribble the kprobe.symbol_name field.  Its only set by the
module when registering the probe.  Modules that exercise good hygiene
using the "const" qualifier will see warnings...

warning: assignment discards qualifiers from pointer target type

Make struct kprobe.symbol_name const char *
