If the pgd is not writable after unpin, weird stuff starts to happen --- the next call to pmd_clear() from free_pte_range() fails in Xen, citing incorrect page types. Can you tell me why linux/xen/the wrpt implementation cannot handle the unpinned pgd being mapped read-only like this? I'll need to see a backtrace, or at least the particular error message from Xen. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
