Make some adjustments to tracepoints to make the tracing a bit more
followable:
(1) Standardise on displaying the backing inode number as "B=<hex>" with
no leading zeros.
(2) Make the cachefiles_lookup tracepoint log the directory inode number
as well as the looked-up inode number.
(3) Add a cachefiles_lookup tracepoint into cachefiles_get_directory() to
log directory lookup.
(4) Add a new cachefiles_mkdir tracepoint and use that to log a successful
mkdir from cachefiles_get_directory().
(5) Make the cachefiles_unlink and cachefiles_rename tracepoints log the
inode number of the affected file/dir rather than dentry struct
pointers.

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.
