Going through the 4.4 BSD book, I learnt that the purpose of the pv_table
is to be able to locate all the mappings to a given physical page.
However, comparing this to the Linux approach, which chains vm_area_struct

mappings, it

Did anyone get a chance to review this ? Is everyone busy or sending

I ran into the same problem as you - and took the time to implement it.
