xfs_lowbit32 implementation

["Barry Naujok" <bnaujok@xxxxxxx>]

More of this libxfs port of the kernel (who cleaned up xfs_bit.*!)...

Anyway...

/* Get low bit set out of 32-bit argument, -1 if none set */
static inline int xfs_lowbit32(__uint32_t v)
{
        unsigned long   t = v;
        return (v) ? find_first_bit(&t, 32) : -1;
}


Couldn't that be:


/* Get low bit set out of 32-bit argument, -1 if none set */
static inline int xfs_lowbit32(__uint32_t v)
{
        return ffs(v) - 1;
}
