Before this patch, function do_xmote would try to sync out the glock dirty data by calling the appropriate glops function XXX_go_sync() but it did not check for a good return code. If the sync was not possible due to an io error or whatever, do_xmote would continue on and call go_inval and release the glock to other cluster nodes. When those nodes go to replay the journal, they may already be holding glocks for the journal records that should have been synced, but were not due to the ignored error. This patch introduces proper error code checking to the go_sync family of glops functions. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Reviewed-by: Andreas Gruenbacher <agruenba@redhat.com> |

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.
