Currently, gfs2 always sets the DLM_LKF_VALBLK flag to enable lvb handling even when sb_lvbptr is NULL. This currently causes no problems because DLM ignores the DLM_LKF_VALBLK flag when sb_lvbptr is NULL, but it does violate the DLM API. Fix that by only setting DLM_LKF_VALBLK when sb_lvbptr is not NULL. Signed-off-by: Alexander Aring <aahringo@redhat.com> 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.
