16 mark_buffer_dirty will set the dirty bit against the buffer, then set
17 its backing page dirty, then tag the page as dirty in its
18 address_space´s radix tree and then attach the address_space´s inode to
19 its superblock´s dirty inode list.

21 mark_buffer_dirty is atomic. It takes
22 bh->b_page->mapping->private_lock, mapping->tree_lock and the global
23 inode_lock.
