Subject: [PATCH v4 06/15] dmaengine: idxd: Add wq private data accessors
Date:   Mon,  8 May 2023 15:07:28 -0500
Message-Id: <038db785a87dc59c0073989633eee0205958cb67.1683573703.git.zanussi@kernel.org>

Add the accessors set_idxd_wq_private() and idxd_wq_private() allowing
users to set and retrieve a private void * associated with an idxd_wq.

The private data is stored in the idxd_dev.conf_dev associated with
each idxd_wq.
