sparse complains about some harmless endianness issues: > drivers/net/ppp/pptp.c:281:21: warning: incorrect type in assignment (different base types) > drivers/net/ppp/pptp.c:281:21: expected unsigned int [usertype] ack > drivers/net/ppp/pptp.c:281:21: got restricted __be32 > drivers/net/ppp/pptp.c:283:23: warning: cast to restricted __be32 Here 'ack' is assigned a value in network-order, and then also the byte-swapped value in host-order. Clean this up by doing the byte-swap as part of the assignment. > drivers/net/ppp/pptp.c:358:26: warning: cast from restricted __be16 > drivers/net/ppp/pptp.c:358:26: warning: incorrect type in argument 1 (different base types) > drivers/net/ppp/pptp.c:358:26: expected unsigned short [usertype] call_id > drivers/net/ppp/pptp.c:358:26: got restricted __be16 [usertype] Here we use the wrong flavour of byte-swap. Use ntohs(), which of course gives the same result.

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.
