memory_barrier

[Bart De Schuymer <bdschuym@pandora.be>]

Hi,

Is there any reason why __memory_barrier() is still referenced in the
kernel source?

grep -r memory_barrier gave the following back, which at first seems to
suggest barrier() is defined using some phantom __memory_barrier(),
quite deceiving...


include/linux/compiler-intel.h:#define barrier() __memory_barrier()
include/linux/compiler.h:# define barrier() __memory_barrier()
include/asm-m32r/system.h: * memory_barrier() for examples and URLs to more information.
include/asm-m32r/system.h: *      memory_barrier();
include/asm-m32r/system.h: *      memory_barrier();
include/asm-i386/system.h: * memory_barrier() for examples and URLs to more information.
include/asm-i386/system.h: *    memory_barrier();
include/asm-i386/system.h: *    memory_barrier();
include/asm-mips/system.h: * memory_barrier() for examples and URLs to more information.
include/asm-mips/system.h: *    memory_barrier();
include/asm-mips/system.h: *    memory_barrier();
include/asm-ia64/intel_intrin.h:void __memory_barrier(void);
include/asm-ia64/intel_intrin.h:#define ia64_barrier()          __memory_barrier()


cheers,
Bart
