[ Upstream commitc8ed1b3593] In gfs2_file_buffered_write(), we currently jump from the second call of function should_fault_in_pages() to above the first call, so should_fault_in_pages() is getting called twice in a row, causing it to accidentally fall back to single-page writes rather than trying the more efficient multi-page writes first. Fix that by moving the retry label to the correct place, behind the first call to should_fault_in_pages().

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.
