Hi Jean,
It seems that the preprocessing of the page faults(groups) here is relatively
generic, and if a device driver wants to reuse it while having its own
iopf_handle_single(),
is there any chance for this? :-)
Thanks,
Shenming

Some systems allow devices to handle I/O Page Faults in the core mm. For
example systems implementing the PCIe PRI extension or Arm SMMU stall
model. Infrastructure for reporting these recoverable page faults was
added to the IOMMU core by commit 0c830e6b3282 ("iommu: Introduce device
