Pull tracing fix from Steven Rostedt:

kernel space or user space.
But the creating of the event format file only checks for 'string' to

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"As the diffstat shows we've had again a lot of works done for this
cycle: the majority of changes are the continued componentization and
code refactoring in ASoC, the tree-wide PCM API updates and cleanups
and SOF updates while a few ASoC driver updates are seen, too.
Here we go, some highlights:
Core:
- Finally y2038 support landed to ALSA ABI; some ioctls have been
extended and lots of tricks were applied
- Applying the new managed PCM buffer API to all drivers; the API
itself was already merged in 5.5
- The already deprecated dimension support in ALSA control API is
dropped completely now
- Verification of ALSA control elements to catch API misuses
ASoC:
- Further code refactorings and moving things to the component level
- Lots of updates and improvements on SOF / Intel drivers; now
including common HDMI driver and SoundWire support
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,
RT1015 and RT1308
HD-audio:
- Improved ring-buffer communications using waitqueue
- Drop the superfluous buffer preallocation on x86
Others:
- Many code cleanups, mostly constifications over the whole tree
- USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
- FireWire: code refactoring for oxfw and dice drivers"

filenames could map to the same no-key name.
- Allow the crypto algorithms used by fscrypt to be built as loadable
modules when the fscrypt-capable filesystems are.
- Optimize fscrypt_zeroout_range().

Pull fs deduplication fix from David Sterba:
"This is a fix for deduplication bug: the last block of two files is
allowed to deduplicated. This got broken in 5.1 by lifting some
generic checks to VFS layer. The affected filesystems are btrfs and
xfs.
The patches are marked for stable as the bug decreases deduplication

Pull btrfs updates from David Sterba:
"Features, highlights:
- async discard
- "mount -o discard=async" to enable it
- freed extents are not discarded immediatelly, but grouped
together and trimmed later, with IO rate limiting
- the "sync" mode submits short extents that could have been
ignored completely by the device, for SATA prior to 3.1 the
requests are unqueued and have a big impact on performance
- the actual discard IO requests have been moved out of
transaction commit to a worker thread, improving commit latency
- IO rate and request size can be tuned by sysfs files, for now
enabled only with CONFIG_BTRFS_DEBUG as we might need to
add/delete the files and don't have a stable-ish ABI for
general use, defaults are conservative
- export device state info in sysfs, eg. missing, writeable
- no discard of extents known to be untouched on disk (eg. after
reservation)
- device stats reset is logged with process name and PID that called
the ioctl
Fixes:
- fix missing hole after hole punching and fsync when using NO_HOLES
- writeback: range cyclic mode could miss some dirty pages and lead
to OOM
- two more corner cases for metadata_uuid change after power loss
during the change
- fix infinite loop during fsync after mix of rename operations
Core changes:
- qgroup assign returns ENOTCONN when quotas not enabled, used to
return EINVAL that was confusing
- device closing does not need to allocate memory anymore
- snapshot aware code got removed, disabled for years due to
performance problems, reimplmentation will allow to select wheter
defrag breaks or does not break COW on shared extents
- tree-checker:
- check leaf chunk item size, cross check against number of
stripes
- verify location keys for DIR_ITEM, DIR_INDEX and XATTR items
- new self test for physical -> logical mapping code, used for super
block range exclusion
- assertion helpers/macros updated to avoid objtool "unreachable
code" reports on older compilers or config option combinations"

Multicast and broadcast packets can be looped from egress to ingress
pre segmentation with dev_loopback_xmit. That function unconditionally
sets ip_summed to CHECKSUM_UNNECESSARY.
udp_rcv_segment segments gso packets in the udp rx path. Segmentation
usually executes on egress, and does not expect packets of this type.
__udp_gso_segment interprets !CHECKSUM_PARTIAL as CHECKSUM_NONE. But
the offsets are not correct for gso_make_checksum.
UDP GSO packets are of type CHECKSUM_PARTIAL, with their uh->check set
to the correct pseudo header checksum. Reset ip_summed to this type.
(CHECKSUM_PARTIAL is allowed on ingress, see comments in skbuff.h)

Pull irq updates from Thomas Gleixner:
"The interrupt departement provides:
- A mechanism to shield isolated tasks from managed interrupts:
The affinity of managed interrupts is completely controlled by the
kernel and user space has no influence on them. The reason is that
the automatically assigned affinity correlates to the multi-queue
CPU handling of block devices.
If the generated affinity mask spaws both housekeeping and isolated
CPUs the interrupt could be routed to an isolated CPU which would
then be disturbed by I/O submitted by a housekeeping CPU.
The new mechamism ensures that as long as one housekeeping CPU is
online in the assigned affinity mask the interrupt is routed to a
housekeeping CPU.
If there is no online housekeeping CPU in the affinity mask, then
the interrupt is routed to an isolated CPU to keep the device queue
intact, but unless the isolated CPU submits I/O by itself these
interrupts are not raised.
- A small addon to the device tree irqdomain core code to avoid
duplication in irq chip drivers
- Conversion of the SiFive PLIC to hierarchical domains

Pull timer updates from Thomas Gleixner:
"The timekeeping and timers departement provides:
- Time namespace support:
If a container migrates from one host to another then it expects
that clocks based on MONOTONIC and BOOTTIME are not subject to
disruption. Due to different boot time and non-suspended runtime
these clocks can differ significantly on two hosts, in the worst
case time goes backwards which is a violation of the POSIX
requirements.
The time namespace addresses this problem. It allows to set offsets
for clock MONOTONIC and BOOTTIME once after creation and before
tasks are associated with the namespace. These offsets are taken
into account by timers and timekeeping including the VDSO.
Offsets for wall clock based clocks (REALTIME/TAI) are not provided
by this mechanism. While in theory possible, the overhead and code
complexity would be immense and not justified by the esoteric
potential use cases which were discussed at Plumbers '18.
The overhead for tasks in the root namespace (ie where host time
offsets = 0) is in the noise and great effort was made to ensure
that especially in the VDSO. If time namespace is disabled in the
kernel configuration the code is compiled out.
Kudos to Andrei Vagin and Dmitry Sofanov who implemented this
feature and kept on for more than a year addressing review
comments, finding better solutions. A pleasant experience.
- Overhaul of the alarmtimer device dependency handling to ensure
that the init/suspend/resume ordering is correct.

- Enforce that the watchdog timestamp is always valid on boot. The

second in the boot process due to truncation of the underlying

The sched clock is divided by 1e9 to convert nanoseconds to
seconds. So for the first second of the boot process the result is
0 which is at the same time the indicator to disable the watchdog.
The trivial fix is to change the disabled indicator to ULONG_MAX.

Pull SELinux update from Paul Moore:
"This is one of the bigger SELinux pull requests in recent years with
28 patches. Everything is passing our test suite and the highlights
are below:
- Mark CONFIG_SECURITY_SELINUX_DISABLE as deprecated. We're some time
away from actually attempting to remove this in the kernel, but the
only distro we know that still uses it (Fedora) is working on
moving away from this so we want to at least let people know we are
planning to remove it.
- Reorder the SELinux hooks to help prevent bad things when SELinux
is disabled at runtime. The proper fix is to remove the
CONFIG_SECURITY_SELINUX_DISABLE functionality (see above) and just
take care of it at boot time (e.g. "selinux=0").
- Add SELinux controls for the kernel lockdown functionality,
introducing a new SELinux class/permissions: "lockdown { integrity
confidentiality }".
- Add a SELinux control for move_mount(2) that reuses the "file {
mounton }" permission.
- Improvements to the SELinux security label data store lookup
functions to speed up translations between our internal label
representations and the visible string labels (both directions).
- Revisit a previous fix related to SELinux inode auditing and
permission caching and do it correctly this time.
- Fix the SELinux access decision cache to cleanup properly on error.
In some extreme cases this could limit the cache size and result in
a decrease in performance.
- Enable SELinux per-file labeling for binderfs.
- The SELinux initialized and disabled flags were wrapped with
accessors to ensure they are accessed correctly.
- Mark several key SELinux structures with __randomize_layout.
- Changes to the LSM build configuration to only build
security/lsm_audit.c when needed.
- Changes to the SELinux build configuration to only build the IB
object cache when CONFIG_SECURITY_INFINIBAND is enabled.
- Move a number of single-caller functions into their callers.
- Documentation fixes (/selinux -> /sys/fs/selinux).
- A handful of cleanup patches that aren't worth mentioning on their
own, the individual descriptions have plenty of detail"
