I think Allocate/Deallocate will need this and Seek will need to do a vm_object_page_clean() as well as the ncl_flush(). I'll look at these once this patch is tested by Alan. Btw, the workaround for any of these problems is "minorversion=3D1" on the mount, for anyone who runs into these issues in unpatched systems. --=20 You are receiving this mail because: You are the assignee for the bug.=
