Select the kernel configuration option CONFIG_S390_VMUR to compile a kernel that supports unit record devices.

Kernel builders: This information is intended for those who want to build their own kernel. Be aware that both compiling your own kernel or recompiling an existing distribution usually means that you have to maintain your kernel yourself.
