[PATCH v2 10/16] dmaengine: idxd: add descs_completed field for completion record

From: Fenghua Yu
Date: Mon Mar 06 2023 - 11:46:14 EST


From: Dave Jiang <dave.jiang@xxxxxxxxx>

The descs_completed field for a completion record is part of a batch
descriptor completion record. It takes the same location as bytes_completed
in a normal descriptor field. Add to expose to user.
