SubjectBitops source problem
Date
From
Hi,

I was just going through the include file in the /usr/include/asm/bitops.h

The function description describes it as non-atomic but it seems it is not.

static __inline__ void __change_bit(int nr, volatile void * addr)
{
__asm__ __volatile__(
"btcl %1,%0"
:"=m" (ADDR)
:"Ir" (nr));
}

The kernel version I am using is 2.6.9-42. Is it right or am I missing something ?

Thanks,
Pravin
