-#ifndef VM_NODUMP
-/*
- * defined here to allow things to compile but technically
- * using this for memory regions will yield in a no-op on newer
- * kernels but on older kernels (v3.3 and older) this bit was used
- * for VM_ALWAYSDUMP. The goal was to remove this bit moving forward
- * and since we can't skip the core dump on old kernels we just make
- * this bit name now a no-op.
- *
- * For details see commits: 909af7 accb61fe cdaaa7003
