This patch series is for the release 3.4. It is reported by Kuwamura that blktap has been broken on ia64. But I think it is broken also on x86.
The change set of 863:464a925d73f1 broken blktap because guest_user_pages() assumes vma->vm_private_data is arrays of struct page*. This patch series fixes it by not keeping vma in struct tap_blkif. Anyway it isn't allowed to keep the pointer to vma without holding the semaphore, mmap_sem. So this patch makes it get mm_struct and use find_vma() to find necessary vma. _______________________________________________ Xen-ia64-devel mailing list Xenfirstname.lastname@example.org http://lists.xensource.com/xen-ia64-devel
