From 72eef0f3af410de2c85f236140ddea61b71cfc3e Mon Sep 17 00:00:00 2001 From: Nikanth Karthikesan Date: Thu, 26 May 2011 16:25:13 -0700 Subject: Documentation/atomic_ops.txt: avoid volatile in sample code As declaring counter as volatile is discouraged, it is best not to use it in sample code as well.

Something like the following should suffice: - typedef struct { volatile int counter; } atomic_t; + typedef struct { int counter; } atomic_t; Historically, counter has been declared volatile. This is now discouraged. See Documentation/volatile-considered-harmful.txt for the complete rationale. -- cgit v1.1
