+    Update Linux kernel version in tst-mman-consts.py.
+    
+    This patch updates the Linux kernel version in tst-mman-consts.py to
+    4.20 (meaning that's the version for which glibc is expected to have
+    the same constants as the kernel, up to the exceptions listed in the
+    test).  (Once we have more such tests sharing common infrastructure, I
+    expect the kernel version will be something set in the infrastructure
+    shared by all such tests, rather than something needing updating
+    separately for each test for each new kernel version.)
+    
+    Tested with build-many-glibcs.py.
+    
+            * sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Expect
+            constants to match with Linux 4.20.
