Once upon a time net/socket.c:dev_ifsioc() used to handle SIOCSHWTSTAMP and SIOCSIFMAP. These have different native and compat layout, so the format conversion had been needed. In 2009 these two cases had been taken out, turning the rest into a convoluted way to calling sock_do_ioctl(). We copy compat structure into native one, call sock_do_ioctl() on that and copy the result back for the in/out ioctls. No layout transformation anywhere, so we might as well just call sock_do_ioctl() and skip all the headache with copying. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> |

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
