Before this patch, if the go_sync operation returned an error during the do_xmote process (such as unable to sync metadata to the journal) the code did goto out. That kept the glock locked, so it could not be given away, which correctly avoids file system corruption. However, it never set the withdraw bit or requeueing the glock work. So it would hang forever, unable to ever demote the glock. This patch changes to goto to a new label, skip_inval, so that errors from go_sync are treated the same way as errors from go_inval: The delayed withdraw bit is set and the work is requeued. That way, the logd should eventually figure out there's a problem and withdraw properly there.

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.
