- Fix DM's passthrough ioctl support to be race free against an underlying device being removed. - Fix corner-case of DM raid resync reporting if/when the raid becomes degraded during resync; otherwise automated raid repair will fail. - A few DM multipath fixes to make non-SCSI optimizations, that were introduced during the 4.16 merge, useful for all non-SCSI devices, rather than narrowly define this non-SCSI mode in terms of "nvme". This allows the removal of "queue_mode nvme" that really didn't need to be introduced. Instead DM core will internalize whether nvme-specific IO submission optimizations are doable and DM multipath will only do SCSI-specific device handler operations if SCSI is in use. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJaou84AAoJEMUj8QotnQNaYucH/RTlx1kJ4S7dHqUVFQdYZoZM ngpBGQZrvcjGwiTqpFb5lbvS4eXL5tAJrmIlcP/vD5woP57kK6uaxWbhZTDKlARK UppM2FwA166szfYLMopA4yPj7o2+aBBF6y6Q9s5kP9UbsNIdBbPGBzz3JhThSu5q FB6YWhMuEpBwQT2Y5nrz/X5mBVnzjPnvCDeYh3HLihnPeYYZiupR9EVCJ7vRVc+S S8+oX6Yl9Jc6GWKQriQW+EEQN/9E6YMH4tTPvd8S5hT6uzznePx8myv60qXM894J f+O9gcna3rF41XIYleUEXbES0kwXZzISeJNo5NokTRIKEmn8fJU+tuvqAGTh/yQ= =1Ki0 -----END PGP SIGNATURE----- Merge tag 'for-4.16/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix an uninitialized variable false warning in dm bufio - Fix DM's passthrough ioctl support to be race free against an underlying device being removed. - Fix corner-case of DM raid resync reporting if/when the raid becomes degraded during resync; otherwise automated raid repair will fail. - A few DM multipath fixes to make non-SCSI optimizations, that were introduced during the 4.16 merge, useful for all non-SCSI devices, rather than narrowly define this non-SCSI mode in terms of "nvme".

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.
