NAME
set_bit - Atomically set a bit in memory
SYNOPSIS
void set_bit(unsigned int nr, volatile unsigned long * addr);
ARGUMENTS

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.
