Description: The latest version of the patch introduces a __cacheline_aligned_in_smp macro. It
The __cacheline_aligned_in_smp macro expands only in the SMP case. It puts the cacheline aligned data in a special section which is only for cacheline aligned data. This guarantees that the cacheline is exclusive for this lock. (There exists also a version of the macro with 4 underscores ____cacheline_aligned_in_smp in cache.h which does not use a separate section, this is not the same, because in this case the cacheline is not exclusive for the lock) |
