__set_bit - Set a bit in memory
SYNOPSIS¶
void __set_bit(long nr, volatile unsigned long * addr);
ARGUMENTS¶
long nr
the bit to set

DESCRIPTION¶
Unlike set_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.
