Fix for the "kmem -z" command on Linux 5.0 and later kernels that
contain commit a921444382b49cc7fdeca3fba3e278bc09484a27, titled
"mm: move zone watermark accesses behind an accessor". Without the
patch, the command fails with the following error message.
kmem: invalid (optional) structure member offsets: zone_pages_min or zone_struct_pages_min
FILE: memory.c LINE: 16457 FUNCTION: dump_zone_stats()
