The domain->default_pasid is not relevant to SVA and it's being cleaned
up by another series. No need to take care of it in this series.
Because ioasid_put() is renamed to ioasid_free() in this patch, without
above changes, this series cannot be compiled.
Thomas and I discussed how to handle aux_domain while you will remove
the entire aux_domain code (https://lore.kernel.org/lkml/87zgnf29op.ffs@tglx/).
The above changes are minimal and temporary changes to compile this series.
The changes will be removed along with the entire aux_domain by your
removing aux_domain series later in 5.18.
Okay. Make sense to me.
Best regards,
baolu
