  • fb9431eb0   bitops kernel-doc: inline instead of macro ... Browse Code »

    Use duplicated inline functions for test_and_set_bit_lock() on x86
    instead of #define macros, thus avoiding a bad example. This allows
    kernel-doc to run cleanly instead of terminating with an error:

    Error(linux-2.6.24-rc1//include/asm-x86/bitops_32.h:188): cannot understand prototype: 'test_and_set_bit_lock test_and_set_bit '

  • 418ccbe37   x86: lock bitops ... Browse Code »

    I missed an obvious one!

    x86 CPUs are defined not to reorder stores past earlier loads, so there is
    no hardware memory barrier required to implement a release-consistent store
    (all stores are, by definition).

    So ditch the generic lock bitops, and implement optimised versions for x86,
    which removes the mfence from __clear_bit_unlock (which is already a useful
    primitive for SLUB).

    forbid asm/bitops.h direct inclusion

    Because of compile errors that may occur after bit changes if asm/bitops.h is
    included directly without e.g. linux/kernel.h which includes linux/bitops.h,
    forbid direct inclusion of asm/bitops.h. Thanks to Adrian Bunk.

    Introduce test_and_set_bit_lock / clear_bit_unlock bitops with lock semantics.
    Convert all architectures to use the generic implementation.
