Andreas Gruenbacher e697fd14db gfs2: Multi-block allocations in gfs2_page_mkwrite
commit f53056c430 upstream.

In gfs2_page_mkwrite's gfs2_allocate_page_backing helper, try to
allocate as many blocks at once as we need.  Pass in the size of the
requested allocation.

Fixes: 35af80aef9 ("gfs2: don't use buffer_heads in gfs2_allocate_page_backing")

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.
