alc 2004-07-28 18:23:08 UTC FreeBSD src repository Modified files: sys/vm vm_object.c Log: Correct a very old error in both vm_object_madvise() (originating in vm/vm_object.c revision 1.88) and vm_object_sync() (originating in vm/vm_map.c revision 1.36): When descending a chain of backing objects, both use the wrong object's backing offset. Consequently, both may operate on the wrong pages. Quoting Matt, "This could be responsible for all of the sporatic madvise oddness that has been reported over the years." Reviewed by: Matt Dillon Revision Changes Path 1.329 +2 -2 src/sys/vm/vm_object.c
