When the GFS2 file system withdraws due to metadata corruption, it often has outstanding transactions in the journal and delayed work queued for its glocks. This patch adds some new checks for a withdrawn file system before proceeding with operations that would obviously cause a BUG() to be triggered. That allows GFS2 to be safely unmounted rather than cause the system to go down. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
