Before this patch, several functions in gfs2 related to the updating of the statfs file used a newly acquired/read buffer_head for the local statfs file. This is completely unnecessary, because other nodes should never update it. Recreating the buffer is a waste of time. This patch allows gfs2 to read in the local statefs buffer_head at mount time and keep it around until unmount time. Signed-off-by: Bob Peterson <rpeterso@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.
