Arnaldo Carvalho de Melo 05f371f8c5 tools headers uapi: Sync linux/usbdevice_fs.h with the kernel sources 
To pick up the changes from:

  4ed3350539 ("USB: usbfs: Add a capability flag for runtime suspend")
  7794f486ed ("usbfs: Add ioctls for runtime power management")

This triggers these changes in the kernel sources, automagically
supporting these new ioctls in the 'perf trace' beautifiers.

Soon this will be used in things like filter expressions for tracepoints
in 'perf record', 'perf trace', 'perf top', i.e. filter expressions will
do a lookup to turn things like USBDEVFS_WAIT_FOR_RESUME into _IO('U',
35) before associating the tracepoint expression to tracepoint perf
event.

README 

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.
