Hi Jason, thanks for all your reviews. Do you have any additional
comments with this series? I'd like this series to be accepted by Vinod
for 5.12-rc if possible. Thanks!

Vinod,
The series fixes the various 'struct device' lifetime handling in the
idxd driver. The devm managed lifetime is incompatible with 'struct device'
objects that resides in the idxd context. Tested with
CONFIG_DEBUG_KOBJECT_RELEASE and address all issues from that.
Please consider for damengine/fixes for the 5.12-rc.
