This module implements support for the eXtra Boot Configuration file
format specified by the Linux kernel. For more information, please see
https://docs.kernel.org/admin-guide/bootconfig.html for more
information.
This is not a strictly-conforming implementation. In particular, this
module does not adhere to the kernel's 32,767-byte restriction and does
not enforce the maximum depth of 16 namespaces.
