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

bh->b_page->mapping->private_lock, mapping->tree_lock and the global
inode_lock.
