David Howells 3aabe01064 kheaders: Ignore silly-rename files 
[ Upstream commit 973b710b88 ]

Tell tar to ignore silly-rename files (".__afs*" and ".nfs*") when building
the header archive.  These occur when a file that is open is unlinked
locally, but hasn't yet been closed.  Such files are visible to the user
via the getdents() syscall and so programs may want to do things with them.

During the kernel build, such files may be made during the processing of
header files and the cleanup may get deferred by fput() which may result in
tar seeing these files when it reads the directory, but they may have
disappeared by the time it tries to open them, causing tar to fail with an
error.  Further, we don't want to include them in the tarball if they still
exist.

With CONFIG_HEADERS_INSTALL=y, something like the following may be seen:

   find: './kernel/.tmp_cpio_dir/include/dt-bindings/reset/.__afs2080': No such file or directory
   tar: ./include/linux/greybus/.__afs3C95: File removed before we read it

The find warning doesn't seem to cause a problem.

Fix this by telling tar when called from in gen_kheaders.sh to exclude such
files.  This only affects afs and nfs; cifs uses the Windows Hidden
attribute to prevent the file from being seen.

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 reStructuredText 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.
