Brian Foster 3cd629e577 mm/fadvise: use LLONG_MAX instead of -1 for eof
generic_fadvise() sets endbyte = -1 to specify end of file (i.e.  if
length == 0 is passed from userspace).  Most other callers to
filemap_fdatawrite_range() use LLONG_MAX for this purpose, particularly if
they also call fdatawait_range() (which requires end >= start).  For
example, sync_file_range(), vfs_fsync() (where the range is passed down
through per-fs ->fsync() callbacks), filemap_flush(), etc. 
generic_fadvise() does not currently wait on writeback, but fix the call
up to be consistent with other callers.

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.
