From 78a9909aab54123c7c471022389b36972e13b48e Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 17 Apr 2008 17:40:51 +0200 Subject: [PATCH] x86, tracing: add notrace to asm-x86/linkage.h notrace signals that a function should not be traced. Most of the time this is used by tracers to annotate code that cannot be traced - it's in a volatile state (such as in user vdso context or NMI context) or it's in the tracer internals.
