Subject: [RESEND PATCH v8 00/11] Fix BUG_ON in vfio_iommu_group_notifier()

Hi Joerg,

This is a resend version of v8 posted here:
https://lore.kernel.org/linux-iommu/20220308054421.847385-1-baolu.lu@linux.intel.com/
as we discussed in this thread:
https://lore.kernel.org/linux-iommu/Yk%2Fq1BGN8pC5HVZp@8bytes.org/

All patches can be applied perfectly except this one:
 - [PATCH v8 02/11] driver core: Add dma_cleanup callback in bus_type
It conflicts with below refactoring commit:
 - 4b775aaf1ea99 "driver core: Refactor sysfs and drv/bus remove hooks"
The conflict has been fixed in this post.

No functional changes in this series. I suppress cc-ing this series to
all v8 reviewers in order to avoid spam.

Please consider it for your iommu tree.

Best regards,
baolu
