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. |
