I can't parse this sentance at all, please simplify or clarify or something so that I understand what is going on here. > This simplifies that. What is "that"? You can't do that for such a complex previous sentence. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

This will be used later by the userspace linker-tables sandbox. As a convenience, include bug.h on kernel.h -- this is not done on upstream kernel.h, however most header files do include bug.h eventually, if we were to only add the ones that need it we'd need to copy a lot of headers to tools for the only purpose of includeing bug.h.
