y'know, this is such an important lock and people have had such problems with it and so many different schemes and ideas have popped up that I'm kinda thinking that we should wrap it:
write_lock_mm(struct mm_struct *mm); write_unlock_mm(struct mm_struct *mm); read_lock_mm(struct mm_struct *mm); read_unlock_mm(struct mm_struct *mm);
so that further experimentations become easier? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
