Linux kernel source tree
ff132c5f93
Before this patch, gfs2's freeze function failed to report an error when the target file system was already frozen as it should (and as generic vfs function freeze_super does. Similarly, gfs2's thaw function failed to report an error when trying to thaw a file system that is not frozen, as vfs function thaw_super does. The errors were checked, but it always returned a 0 return code. This patch adds the missing error return codes to gfs2 freeze and thaw.

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.
