Or > create a new, standalone work_struct.h - that looks pretty simple. I tried to move out work_struct, it didn't help. There are actually several circular dependencies that ends in bitmap.h either way or another. First one is slab.h -> gfp.h -> mmzone.h -> nodemask.h -> bitmap.h And so on... Splitting out kXalloc stuff to a separate header won't help, I think, because of the above. Splitting out struct work_struct is just a tip of an iceberg. Splitting out memcg stuff won't help in the similar way. I'm all ears for (a better) solution. -- With Best Regards, Andy Shevchenko -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
