I did not expect you to use my remark as an excuse for dropping the
ball. What I meant is that maybe, there is a way to skip the call to
__ipipe_pin_mapping_globally() entirely in the upper layers, for the
"huge pages" case. And if there is, this should be preferred over
patching vmalloc_sync_one, a function not meant to be used for huge
mappings anyway.
