/*************************************************************************** * This routine walks through an ASM list and marks the PDAs that have * failed. It's called only when a disk failure causes an in-flight * DAG to fail. The parity may consist of two components, but we want * to use only one failedPDA pointer. Thus we set failedPDA to point * to the first parity component, and rely on the rest of the code to * do the right thing with this. ***************************************************************************/
