  • This patch introduces the C-language equivalents of the functions below:

    void set_bit(int nr, volatile unsigned long *addr);
    void clear_bit(int nr, volatile unsigned long *addr);
    void change_bit(int nr, volatile unsigned long *addr);
    int test_and_set_bit(int nr, volatile unsigned long *addr);
    int test_and_clear_bit(int nr, volatile unsigned long *addr);
    int test_and_change_bit(int nr, volatile unsigned long *addr);

    In include/asm-generic/bitops/atomic.h

    This code largely copied from:

    include/asm-powerpc/bitops.h
    include/asm-parisc/bitops.h
