|

*
|
|
* Normally, each list contains one dag for the entire stripe. In some
|
|
* tricky cases, we break this into multiple dags, either one per stripe
|
|
* unit or one per block (sector). When this occurs, these dags are returned
|
|
* as a linked list (dagList) which is executed sequentially (to preserve
|
|
* atomic parity updates in the stripe).
|
|
*
|
|
* dags which operate on independent parity goups (stripes) are returned in
|
|
* independent dagLists (distinct elements in desc->dagArray) and may be
|
|
* executed concurrently.
|
|
*
|
|
* Finally, if the SelectionFunc fails to create a dag for a block, we punt
|
|
* and return 1.
|
|
*
|
|
* The above process is performed in two phases:
|
|
* 1) create an array(s) of creation functions (eg stripeFuncs)
|
|
* 2) create dags and concatenate/merge to form the final dag.
|
|
*
|
|
* Because dag's are basic blocks (single entry, single exit, unconditional
|
|
* control flow, we can add the following optimizations (future work):
|
|
* first-pass optimizer to allow max concurrency (need all data dependencies)
|
|
* second-pass optimizer to eliminate common subexpressions (need true
|
|
* data dependencies)
|
|
* third-pass optimizer to eliminate dead code (need true data dependencies)
