- A few request-based DM and DM multipath fixes for issues that were made when merging Christoph's changes with Bart's changes for 4.12 - A DM bufio unsigned overflow fix - A couple pure fixes for the DM cache target. - Various very small tweaks to the DM cache target that enable considerable speed improvements in the face of continuous IO. Given that the cache target was significantly reworked for 4.12 I see no reason to sit on these advances until 4.13 considering the favorable results associated with such minimalist tweaks. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJZHJ6hAAoJEMUj8QotnQNazb4H/2i+OdNU3qEv0wg0Vf2fdWbU M0FYLDwuEBx+/RCBoJbjLY4enfup2Ak4ykxivt1gDZL4sBY8bsf/jxjgTKD1icp4 tV+6tLFbzVZwp2JtDgbWJ0FuYEfINxNwVJYRUY6dbgsWQPCxKwYAYnYa102no78t pqykpj/jfQB5ru5bNDVC/KcV8fj+3mc4H7IJxGeEnVzoXyW6wsnvP+6FqOHnuocE HU2zCzit1nfLtI7eL3I3B5nQKVtkPZoR/ILFyo7viU1EKA9zNEjkLI7EOKrMvPNC b0H6lqMkoBIWDw22sxkk/utpywFVqQ1K7kyAWTa1XsSsSvritSmZP2k+dCEkk/U= =5lrV -----END PGP SIGNATURE----- Merge tag 'for-4.12/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - a couple DM thin provisioning fixes - a few request-based DM and DM multipath fixes for issues that were made when merging Christoph's changes with Bart's changes for 4.12 - a DM bufio unsigned overflow fix - a couple pure fixes for the DM cache target. - various very small tweaks to the DM cache target that enable considerable speed improvements in the face of continuous IO.

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.
