Dear Maintainers,

I have been using the IDXD driver to experiment with the upcoming core
changes in support of IMS ([1], [2], [3]). As part of this work I
happened to exercise the error paths within IDXD and encountered
a few issues that are addressed in this series. These changes are
independent from IMS and just aims to make the IDXD driver more
robust against errors.

Your feedback is greatly appreciated.

Reinette
