[PATCH 0/1] [PULL REQUEST] iommu/vt-d: Fixes for v6.17-rc

Posted by Lu Baolu 1 month ago

Hi Joerg,

The following fix has been queued for v6.17-rc:

- Fix __domain_mapping()'s usage of switch_to_super_page()

It fixes a bug in __domain_mapping() where valid PTEs that are beyond
the affected huge page range might be zeroed out. The patch has been
reviewed and tested and is ready for merge. Please consider it for
v6.17-rc.

Best regards,
baolu
