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. It is not clear to me if these are appropriate for stable so I am not including the stable team. Please let me know if you think otherwise and I can add the necessary Cc. With the refactoring through the history of the driver I was not able to identify a Fixes: candidate for all. Patch #3 does look to be a potentially complicated backport. Your feedback is greatly appreciated.
