SET_BIT(9)		   Basic C Library Functions		    SET_BIT(9)

NAME
       set_bit - Atomically set a bit in memory

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

ARGUMENTS
       nr
	   the bit to set

       addr
	   the address to start counting from

DESCRIPTION
       This function is atomic and may not be reordered. See __set_bit if you
       do not require the atomic guarantees.

NOTE
       there are no guarantees that this function will not be reordered on non
       x86 architectures, so if you are writing portable code, make sure not
       to rely on its reordering guarantees.

       Note that nr may be almost arbitrarily large; this function is not
       restricted to acting on a single-word quantity.
