Commit65b32f801b("uapi: move IPPROTO_L2TP to in.h") moved the definition of IPPROTO_L2TP from a define to an enum, but since __stringify doesn't work properly with enums, we ended up breaking the modalias strings for the l2tp modules: $ modinfo l2tp_ip l2tp_ip6 | grep alias alias: net-pf-2-proto-IPPROTO_L2TP alias: net-pf-2-proto-2-type-IPPROTO_L2TP alias: net-pf-10-proto-IPPROTO_L2TP alias: net-pf-10-proto-2-type-IPPROTO_L2TP Use the resolved number directly in MODULE_ALIAS_*() macros (as we already do with SOCK_DGRAM) to fix the alias strings: $ modinfo l2tp_ip l2tp_ip6 | grep alias alias: net-pf-2-proto-115 alias: net-pf-2-proto-115-type-2 alias: net-pf-10-proto-115 alias: net-pf-10-proto-115-type-2 Moreover, fix the ordering of the parameters passed to MODULE_ALIAS_NET_PF_PROTO_TYPE() by switching proto and type.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
