inefficiencies in the on-disk journal device layout. Another that makes use of the block layer's on-stack plugging when writing the journal. - A dm-bufio fix for the blk_status_t conversion that went in during the merge window. - A few DM raid fixes that address correctness when suspending the device and a validation fix for validation that occurs during device activation. - A couple DM zoned target fixes. Important one being the fix to not use GFP_KERNEL in the IO path due to concerns about deadlock in low-memory conditions (e.g. swap over a DM zoned device, etc). - A DM DAX device fix to make sure dm_dax_flush() is called if the underlying DAX device is operating as a write cache. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJZe13OAAoJEMUj8QotnQNav/gIAMXMUbXlYHVikVNq+6rNkXRk FlsltNcJEDeZCit0nJd/2nOWGpssXdz+7cJTUU28Kp+3IscIolSHS51bzfSFI05V 7LbYqEX1EdXkTwEeYfHlAoOexvj4oarpAWWQF/ACU8rHCruaqfqIa57mstxLoyDY XcxsIY/fds6GZViLB0MD/jBAKaLWX90aFZ9MQcF7AmdpMr56kCO2PUhiqHcrN47t BjH7E5QSKGl2pMND1bR6pleWFw8HB7h82Qjaasd5bQuVWseQ4u9Illxny6bhhk2E BiEWjzFvZB+JL1zl7JIXnBjhdmbwgAVvoW6EqHuVzHuR0X8gylBF2gDLnSzUZu4= =3MxS -----END PGP SIGNATURE----- Merge tag 'for-4.13/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - a few DM integrity fixes that improve performance.

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.
