| Thread-topic: | why would XENMEM_decrease_reservation fail? |
I am attempting to implement the kludge to make save/restore/migrate work in the GPLPV drivers under Xen 3.4.1. On my test box I successfully free grant_table_pages + 1 pages. The logs from another users system show that each call to XENMEM_decrease_reservation returns 0 instead of 1. Under what circumstances would XENMEM_decrease_reservation fail? The pfn passed to XENMEM_decrease_reservation looks reasonable (similar values to my test box), and everything else is identical.
