DESCRIPTION

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.
20
21       mark_buffer_dirty is atomic. It takes
22       bh->b_page->mapping->private_lock, mapping->tree_lock and
23       mapping->host->i_lock.
