__CHANGE_BIT(9)		   Basic C Library Functions	       __CHANGE_BIT(9)

NAME
       __change_bit - Toggle a bit in memory

SYNOPSIS
       void __change_bit(int nr, volatile unsigned long * addr);

ARGUMENTS
       nr
	   the bit to change

       addr
	   the address to start counting from

DESCRIPTION
       Unlike change_bit, this function is non-atomic and may be reordered. If
       it's called on the same region of memory simultaneously, the effect may
       be that only one operation succeeds.
