If this WARN_ON triggers it speaks to programmer error, and likely implies corruption, but no released kernel should trigger it. This WARN_ON serves to assist DM integrity developers as changes are made/tested in the future. BUG_ON is excessive for catching programmer error, if a user or developer would like warnings to trigger a panic, they can enable that via /proc/sys/kernel/panic_on_warn Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@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.
