| 131 | Return If __builtin_constant_p( Block is followed by a discontiguity ) Then constant_test_bit(( Block is followed by a discontiguity ), ( & buffer state bitmap (see above) )) Else variable_test_bit(( Block is followed by a discontiguity ), ( & buffer state bitmap (see above) )) |

| do_direct_IO | Walk the user pages, and the file, mapping blocks to disk and generating* a sequence of (page,offset,len,block) mappings. These mappings are injected* into submit_page_section(), which takes care of the next stage of submission |
| do_mpage_readpage | This is the worker routine which does all the work of mapping the disk* blocks and constructs largest possible bios, submits them for IO if the* blocks are not contiguous on the disk |
