Pull io_uring updates from Jens Axboe:
"Highlights from this cycles are things like request recycling and
task_work optimizations, which net us anywhere from 10-20% of speedups
on workloads that mostly are inline.
This work was originally done to put io_uring under memcg, which adds
considerable overhead. But it's a really nice win as well. Also worth
highlighting is the LOOKUP_CACHED work in the VFS, and using it in
io_uring. Greatly speeds up the fast path for file opens.
Summary:
- Put io_uring under memcg protection. We accounted just the rings
themselves under rlimit memlock before, now we account everything.
- Request cache recycling, persistent across invocations (Pavel, me)
- First part of a cleanup/improvement to buffer registration (Bijan)
- SQPOLL fixes (Hao)
- File registration NULL pointer fixup (Dan)
- LOOKUP_CACHED support for io_uring
- Disable /proc/thread-self/ for io_uring, like we do for /proc/self
- Add Pavel to the io_uring MAINTAINERS entry
- Tons of code cleanups and optimizations (Pavel)
- Support for skip entries in file registration (Noah)"

Pull iomap updates from Darrick Wong:
"The big change in this cycle is some new code to make it possible for
XFS to try unaligned directio overwrites without taking locks. If the
block is fully written and within EOF (i.e. doesn't require any
further fs intervention) then we can let the unlocked write proceed.
If not, we fall back to synchronizing direct writes.
Summary:
- Adjust the final parameter of iomap_dio_rw.
- Add a new flag to request that iomap directio writes return EAGAIN
if the write is not a pure overwrite within EOF; this will be used
to reduce lock contention with unaligned direct writes on XFS.
- Amend XFS' directio code to eliminate exclusive locking for
unaligned direct writes if the circumstances permit"

Pull f2fs updates from Jaegeuk Kim:
"We've added two major features: 1) compression level and 2)
checkpoint_merge, in this round.
Compression level expands 'compress_algorithm' mount option to accept
parameter as format of <algorithm>:<level>, by this way, it gives a
way to allow user to do more specified config on lz4 and zstd
compression level, then f2fs compression can provide higher compress
ratio.
checkpoint_merge creates a kernel daemon and makes it to merge
concurrent checkpoint requests as much as possible to eliminate
redundant checkpoint issues. Plus, we can eliminate the sluggish issue
caused by slow checkpoint operation when the checkpoint is done in a
process context in a cgroup having low i/o budget and cpu shares.
Enhancements:
- add compress level for lz4 and zstd in mount option
- checkpoint_merge mount option
- deprecate f2fs_trace_io
Bug fixes:
- flush data when enabling checkpoint back
- handle corner cases of mount options
- missing ACL update and lock for I_LINKABLE flag
- attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
- fix potential deadlock in compression flow
- fix wrong submit_io condition
As usual, we've cleaned up many code flows and fixed minor bugs"

Pull btrfs updates from David Sterba:
"This brings updates of space handling, performance improvements or bug
fixes. The subpage block size and zoned mode features have reached
state where they're usable but with limitations.
Performance or related:
- do not block on deleted block group mutex in the cleaner, avoids
some long stalls
- improved flushing: make it work better with ticket space
reservations and avoid excessive transaction commits in some
scenarios, slightly improves throughput for random write load
- preemptive background flushing: separate the logic from ticket
reservations, improve the accounting and decisions when to flush in
low space conditions
- less lock contention related to running delayed refs, let just one
thread do the flushing when there are many inside transaction
commit
- dbench workload improvements: avoid unnecessary work when logging
inodes, fewer fallbacks to transaction commit and thus less waiting
for it (+7% throughput, -20% latency)
Core:
- subpage block size
- currently read-only support
- refactor and generalize code where sectorsize is assumed to be
page size, add the subpage handling everywhere
- the read-write support is on the way, page sizes are still
limited to 4K or 64K
- zoned mode, first working version but with limitations
- SMR/ZBC/ZNS friendly allocation mode, utilizing the "no fixed
location for structures" and chunked allocation
- superblock as the only fixed data structure needs special
handling, uses 2 consecutive zones as a ring buffer
- tree-log support with a dedicated block group to avoid unordered
writes
- emulated zones on non-zoned devices
- not yet working
- all non-single block group profiles, requires more zone write
pointer synchronization between the multiple block groups
- fitrim due to dependency on space cache, can be implemented
Fixes:
- ref-verify: proper tree owner and node level tracking
- fix pinned byte accounting, causing some early ENOSPC now more
likely due to other changes in delayed refs
Other:
- error handling fixes and improvements
- more error injection points
- more function documentation
- more and updated tracepoints
- subset of W=1 checked by default
- update comments to allow more automatic kdoc parameter checks"

Pull ARM SoC platform removals from Arnd Bergmann:
"There are a lot of platforms that have not seen any interesting code
changes in the past five years or more.
I made a list and asked around which ones are no longer in use, and
received confirmation about six ARM platforms and the TI C6x
architecture that have all reached the end of their life upstream,
with no known users remaining:
- efm32 - added in 2011, first Cortex-M, no notable changes after 2013
- picoxcell - added in 2011, abandoned after 2012 acquisition
- prima2 - added in 20111, no notable changes since 2015
- tango - added in 2015, sporadic changes until 2017, but abandoned
- u300 - added in 2009, no notable changes since 2013
- zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes
- arch/c6x - added in 2011, but work stalled soon after that
A number of other platforms on the original list turned out to still
have users. In some cases there are out-of-tree patches and users that
plan to contribute them in the future, in other cases the code is
complete and works reliably"

Add support for offloading MRP in HW. Currently implement the switchdev
calls 'SWITCHDEV_OBJ_ID_MRP', 'SWITCHDEV_OBJ_ID_RING_ROLE_MRP',
to allow to create MRP instances and to set the role of these instances.
Add DSA_NOTIFIER_MRP_ADD/DEL and DSA_NOTIFIER_MRP_ADD/DEL_RING_ROLE
which calls to .port_mrp_add/del and .port_mrp_add/del_ring_role in the
DSA driver for the switch.

Add basic support for MRP. The HW will just trap all MRP frames on the
ring ports to CPU and allow the SW to process them. In this way it is
possible to for this node to behave both as MRM and MRC.
Current limitations are:
- it doesn't support Interconnect roles.
- it supports only a single ring.
- the HW should be able to do forwarding of MRP Test frames so the SW
will not need to do this. So it would be able to have the role MRC
without SW support.

Add the member sw_backup to the structures switchdev_obj_ring_role_mrp
and switchdev_obj_in_role_mrp. In this way the SW can call the driver in
2 ways, once when sw_backup is set to false, meaning that the driver
should implement this completely in HW. And if that is not supported the
SW will call again but with sw_backup set to true, meaning that the
HW should help or allow the SW to run the protocol.
For example when role is MRM, if the HW can't detect when it stops
receiving MRP Test frames but it can trap these frames to CPU, then it
needs to return -EOPNOTSUPP when sw_backup is false and return 0 when
sw_backup is true.

Some internal PHY's have their events like link change reported by the
MAC interrupt. We have PHY_IGNORE_INTERRUPT to deal with this scenario.
I'm not too happy with this name. We don't ignore interrupts, typically
there is no interrupt exposed at a PHY level. So let's rename it to
PHY_MAC_INTERRUPT. This is in line with phy_mac_interrupt(), which is
called from the MAC interrupt handler to handle PHY events.

We have a number of unused flags defined today and since we are scarce
on space and may need to introduce new flags in the future remove and
shift every existing flag down into a contiguous assignment.
PHY_BCM_FLAGS_MODE_1000BX was only used internally for the BCM54616S
PHY, so we allocate a driver private structure instead to store that
flag instead of canibalizing one from phydev->dev_flags for that
purpose.

A userspace daemon like firewalld might need to monitor for netlink
updates to detect its ruleset removal by the (global) flush ruleset
command to ensure ruleset persistency. This adds extra complexity from
userspace and, for some little time, the firewall policy is not in
place.
This patch adds the NFT_TABLE_F_OWNER flag which allows a userspace
program to own the table that creates in exclusivity.
Tables that are owned...
- can only be updated and removed by the owner, non-owners hit EPERM if
they try to update it or remove it.
- are destroyed when the owner closes the netlink socket or the process
is gone (implicit netlink socket closure).
- are skipped by the global flush ruleset command.
- are listed in the global ruleset.
The userspace process that sets on the NFT_TABLE_F_OWNER flag need to
leave open the netlink socket.
A new NFTA_TABLE_OWNER netlink attribute specifies the netlink port ID
to identify the owner from userspace.
This patch also updates error reporting when an unknown table flag is
specified to change it from EINVAL to EOPNOTSUPP given that EINVAL is
usually reserved to report for malformed netlink messages to userspace.
