In this round, we've added new features such as zone capacity for ZNS and
a new GC policy, ATGC, along with in-memory segment management. In addition,
we could improve the decompression speed significantly by changing virtual
mapping method. Even though we've fixed lots of small bugs in compression
support, I feel that it becomes more stable so that I could give it a try in
production.
Enhancement:
- suport zone capacity in NVMe Zoned Namespace devices
- introduce in-memory current segment management
- add standart casefolding support
- support age threshold based garbage collection
- improve decompression speed by changing virtual mapping method
Bug fix:
- fix condition checks in some ioctl() such as compression, move_range, etc
- fix 32/64bits support in data structures
- fix memory allocation in zstd decompress
- add some boundary checks to avoid kernel panic on corrupted image
- fix disallowing compression for non-empty file
- fix slab leakage of compressed block writes
In addition, it includes code refactoring for better readability and minor
bug fixes for compression and zoned device support.

Pull documentation updates from Mauro Carvalho Chehab:
"A series of patches addressing warnings produced by make htmldocs.
This includes:
- kernel-doc markup fixes
- ReST fixes
- Updates at the build system in order to support newer versions of
the docs build toolchain (Sphinx)
After this series, the number of html build warnings should reduce
significantly, and building with Sphinx 3.1 or later should now be
supported (although it is still recommended to use Sphinx 2.4.4).
As agreed with Jon, I should be sending you a late pull request by the
end of the merge window addressing remaining issues with docs build,
as there are a number of warning fixes that depends on pull requests
that should be happening along the merge window.
The end goal is to have a clean htmldocs build on Kernel 5.10.
PS. It should be noticed that Sphinx 3.0 is not currently supported,
as it lacks support for C domain namespaces. Such feature, needed in
order to document uAPI system calls with Sphinx 3.x, was added only on
Sphinx 3.1"

In commit 16ad3f4022
("tipc: introduce variable window congestion control"), we applied
the algorithm to select window size from minimum window to the
configured maximum window for unicast link, and, besides we chose
to keep the window size for broadcast link unchanged and equal (i.e
fix window 50)
However, when setting maximum window variable via command, the window
variable was re-initialized to unexpect value (i.e 32).
We fix this by updating the fix window for broadcast as we stated.

The queue limit of the broadcast link is being calculated base on initial
MTU. However, when MTU value changed (e.g manual changing MTU on NIC
device, MTU negotiation etc.,) we do not re-calculate queue limit.
This gives throughput does not reflect with the change.
So fix it by calling the function to re-calculate queue limit of the
broadcast link.

On some panels hooked up to the ti-sn65dsi86 bridge chip we found that
link training was failing. Specifically, we'd see:
ti_sn65dsi86 2-002d: [drm:ti_sn_bridge_enable] *ERROR* Link training failed, link is off (-5)
The panel was hooked up to a logic analyzer and it was found that, as
part of link training, the bridge chip was writing a 0x1 to DPCD
address 00600h and the panel responded NACK. As can be seen in header
files, the write of 0x1 to DPCD address 0x600h means we were trying to
write the value DP_SET_POWER_D0 to the register DP_SET_POWER. The
panel vendor says that a NACK in this case is not unexpected and means
"not ready, try again".
In testing, we found that this panel would respond with a NACK in
about 1/25 times. Adding the retry logic worked fine and the most
number of tries needed was 3. Just to be safe, we'll add 10 tries
here and we'll add a little blurb to the logs if we ever need more
than 5.

Patch series "add fault injection to user memory access", v3.
The goal of this series is to improve testing of fault-tolerance in usages
of user memory access functions, by adding support for fault injection.
syzkaller/syzbot are using the existing fault injection modes and will use
this particular feature also.
The first patch adds failure injection capability for usercopy functions.
The second changes usercopy functions to use this new failure capability
(copy_from_user, ...). The third patch adds get/put/clear_user failures
to x86.
This patch (of 3):
Add a failure injection capability to improve testing of fault-tolerance
in usages of user memory access functions.
Add CONFIG_FAULT_INJECTION_USERCOPY to enable faults in usercopy
functions. The should_fail_usercopy function is to be called by these
functions (copy_from_user, get_user, ...) in order to fail or not.
