Hi, Here is an updated version of the patch. It's similar to the original except that I moved the lookup for the blktap info struct after the check for vma->vm_file. The reason is that the mmap code sets vm_file to NULL on failure. cheers geoffrey On 6/1/07, Isaku Yamahata <yamahata@xxxxxxxxxxxxx> wrote: Various fixes blktap_clear_pte(). added pte_get_and_clear_full() for auto translated physmap mode. added pte_get_and_clear_full() for io ring page. fix index calculation of map[]. This function is always called so that removed warning. -- yamahata _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
