Hi, These patches contain changes to the kernel blktap code. The main change is the addition of a vma hook to clear ptes when linux implicitly releases a vma. This allows the block tap to release grants when a user level process such as tapdisk crashes. This fixes the problem of Xen killing a domain because of implicit grant unmapping. The patches should apply cleanly to changeset 15080. Comments are most welcome. Thanks, geoffrey _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
