write_boundary_block | Called when we've recently written block `bblock', and it is known that* `bblock' was for a buffer_boundary() buffer. This means that the block at* `bblock + 1' is probably a dirty indirect block. Hunt it down and, if it's* dirty, schedule it for IO |
__breadahead | Do async read-ahead on a buffer.. |
