The quota sync generation is only ever updated under sd_quota_sync_mutex by gfs2_quota_sync(), but its current value is fetched ouside of that mutex, so use WRITE_ONCE() and READ_ONCE() when accessing it without holding that mutex. Pass the current sync generation to do_sync() from its callers to ensure that we're not recording the wrong generation when the syncing is done. Also, make sure that qd->qd_sync_gen only ever moves forward. In gfs2_quota_sync(), only write the new sync generation when we know that there are changes. This eliminates the need for function sd_changed(), which we will remove in the next commit. Signed-off-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 reStructuredText 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.
