small_io_total_bytes_fix.patch:
Fixed an issue with the small I/O total size being passed to the
trove_bstream_write_list(). The uint32_t was being casted to
(TROVE_size *)&s_op->req->u.small_io.total_bytes on line 162 of
small_io.sm.
process_multiple_aiocbs.patch:
Fixed the dbpf_bstream_listio_convert() function to actually handle more
than a single aiocb at a time. This should boost noncontiguous I/O
performance quite a bit.
