Pull device mapper fixes from Mike Snitzer: - DM cache metadata fixes to short-circuit operations that require the metadata not be in 'fail_io' mode. Otherwise crashes are possible. - a DM cache fix to address the inability to adapt to continuous IO that happened to also reflect a changing working set (which required old blocks be demoted before the new working set could be promoted) - a DM cache smq policy cleanup that fell out from reviewing the above - fix the Kconfig help text for CONFIG_DM_INTEGRITY * tag 'for-4.12/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm cache metadata: fail operations if fail_io mode has been established dm integrity: improve the Kconfig help text for DM_INTEGRITY dm cache policy smq: cleanup free_target_met() and clean_target_met() dm cache policy smq: allow demotions to happen even during 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.
