Before this patch, an io error, such as -EIO writing to the journal would cause function gfs2_freeze to go into an infinite loop, continuously retrying the freeze operation. But nothing ever clears the -EIO except unmount after withdraw, which is impossible if the freeze operation never ends (fails). Instead you get: [ 6499.767994] gfs2: fsid=dm-32.0: error freezing FS: -5 [ 6499.773058] gfs2: fsid=dm-32.0: retrying... [ 6500.791957] gfs2: fsid=dm-32.0: error freezing FS: -5 [ 6500.797015] gfs2: fsid=dm-32.0: retrying... This patch adds a check for -EIO in gfs2_freeze, and if seen, it dequeues the freeze glock, aborts the loop and returns the error. Also, there's no need to pass the freeze holder to function gfs2_lock_fs_check_clean since it's only called in one place and it's a well-known superblock pointer, so this simplifies that.

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.
