NAME

       __change_bit -  Toggle a bit in memory

SYNOPSIS

       void __change_bit (int nr, volatile void *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.
