Eg, vm_start is modified by expand_stack(), it is hard to come up with a destructive scenario without having the vmlist protection in this case. -The page_table_lock nests with the inode i_mmap_lock and the kmem cache +The page_table_lock nests with the inode i_mmap_mutex and the kmem cache c_spinlock spinlocks. This is okay, since the kmem code asks for pages after dropping c_spinlock. The page_table_lock also nests with pagecache_lock and pagemap_lru_lock spinlocks, and no code asks for memory with these locks |
