gnu asm help...

[Raj, Ashok]

Hello asm gurus..

I need a simple (??) change to atomic_inc() functionality. so that i can
increment and return the 
value of the variable.

current implementation in linux/include/asm/atomic.h does not do this job.

any help would be greatly appreciated.

from atomic.h

also if there is any reference to the gnu asm symtax, please send me a
pointer.. 
i can understand what the LOCK "incl %0 means.. but not sure what the rest
is for.

thanks
ashokr

static __inline__ void atomic_inc(atomic_t *v)
{
    __asm__ __volatile__(
        LOCK "incl %0"
        :"=m" (v->counter)
        :"m" (v->counter));
}
