commit6f83ab22adupstream. -1 tells use to use the current position, but we check if the file is a stream regardless of that. Fix up io_kiocb_update_pos() to only dip into file if we need to. This is both more efficient and also drops 12 bytes of text on aarch64 and 64 bytes on x86-64.

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.
