Andreas Gruenbacher 0777fe98a4 gfs2: gfs2_setattr_size error path fix 
[ Upstream commit 7336905a89 ]

When gfs2_setattr_size() fails, it calls gfs2_rs_delete(ip, NULL) to get
rid of any reservations the inode may have.  Instead, it should pass in
the inode's write count as the second parameter to allow
gfs2_rs_delete() to figure out if the inode has any writers left.

In a next step, there are two instances of gfs2_rs_delete(ip, NULL) left
where we know that there can be no other users of the inode.  Replace
those with gfs2_rs_deltree(&ip->i_res) to avoid the unnecessary write
count check.

With that, gfs2_rs_delete() is only called with the inode's actual write
count, so get rid of the second parameter.

Fixes: a097dc7e24 ("GFS2: Make rgrp reservations part of the gfs2_inode structure")

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 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.
