Merge tag 'for-4.17-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"There are a several user visible changes, the rest is mostly invisible
and continues to clean up the whole code base.
User visible changes:
- new mount option nossd_spread (pair for ssd_spread)
- mount option subvolid will detect junk after the number and fail
the mount
- add message after cancelled device replace
- direct module dependency on libcrc32, removed own crc wrappers
- removed user space transaction ioctls
- use lighter locking when reading /proc/self/mounts, RCU instead of
mutex to avoid unnecessary contention
Enhancements:
- skip writeback of last page when truncating file to same size
- send: do not issue unnecessary truncate operations
- mount option token specifiers: use %u for unsigned values, more
validation
- selftests: more tree block validations
qgroups:
- preparatory work for splitting reservation types for data and
metadata, this should allow for more accurate tracking and fix some
issues with underflows or do further enhancements
- split metadata reservations for started and joined transaction so
they do not get mixed up and are accounted correctly at commit time
- with the above, it's possible to revert patch that potentially
deadlocks when trying to make more space by explicitly committing
when the quota limit is hit
- fix root item corruption when multiple same source snapshots are
created with quota enabled
RAID56:
- make sure target is identical to source when raid56 rebuild fails
after dev-replace
- faster rebuild during scrub, batch by stripes and not
block-by-block
- make more use of cached data when rebuilding from a missing device
Fixes:
- null pointer deref when device replace target is missing
- fix fsync after hole punching when using no-holes feature
- fix lockdep splat when allocating percpu data with wrong GFP flags
Cleanups, refactoring, core changes:
- drop redunant parameters from various functions
- kill and opencode trivial helpers
- __cold/__exit function annotations
- dead code removal
- continued audit and documentation of memory barriers
- error handling: handle removal from uuid tree
- error handling: remove handling of impossible condtitons
- more debugging or error messages
- updated tracepoints
- one VLA use removal (and one still left)"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
