[ Upstream commit7336905a89] 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.

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.
