cfq: Disable writeback throttling by default
Writeback throttling does not play well with CFQ since that also tries
to throttle async writes. As a result async writeback can get starved in
presence of readers. As an example take a benchmark simulating
postgreSQL database running over a standard rotating SATA drive. There
are 16 processes doing random reads from a huge file (2*machine memory),
1 process doing random writes to the huge file and calling fsync once
per 50000 writes and 1 process doing sequential 8k writes to a
relatively small file wrapping around at the end of the file and calling
fsync every 5 writes. Under this load read latency easily exceeds the
target latency of 75 ms (just because there are so many reads happening
against a relatively slow disk) and thus writeback is throttled to a
point where only 1 write request is allowed at a time. Blktrace data
then looks like:

So we can see a Q event for a write request, then IO is blocked by
writeback throttling and G and I events for the request happen only once
other writeback IO is completed. Thus CFQ always sees only one write
request. When it sees it, it queues the async queue behind all the read
queues and the async queue gets scheduled after about one second. When
it is scheduled, that one request gets dispatched and async queue is
expired as it has no more requests to submit. Overall we submit about
one write request per second.
Although this scheduling is beneficial for read latency, writes are
heavily starved and this causes large delays all over the system (due to
processes blocking on page lock, transaction starts, etc.). When
writeback throttling is disabled, write throughput is about one fifth of
a read throughput which roughly matches readers/writers ratio and
overall the system stalls are much shorter.
Mixing writeback throttling logic with CFQ throttling logic is always a
recipe for surprises as CFQ assumes it sees the big part of the picture
which is not necessarily true when writeback throttling is blocking
requests. So disable writeback throttling logic by default when CFQ is
used as an IO scheduler.

Generic XDP
This provides a generic non-optimized XDP implementation when the
device driver does not provide an optimized one.
It is arguable that perhaps I should have required something like
this as part of the initial XDP feature merge.
I believe this is critical for two reasons:
1) Accessibility. More people can play with XDP with less
dependencies. Yes I know we have XDP support in virtio_net, but
that just creates another depedency for learning how to use this
facility.
I wrote this to make life easier for the XDP newbies.
2) As a model for what the expected semantics are. If there is a pure
generic core implementation, it serves as a semantic example for
driver folks adding XDP support.
This is just a rough draft and is untested.

Re: [LKP] LKP report for aubrey-fast_idle/4.8.x [job.yaml]
by Li, Aubrey
Hi Philip,
It seems that I always encountered an error below so that the test is always incomplete.
Can you please take a look?
Thanks,

[ACPI: battery] 4d3c75a57e: BUG: KASAN: stack-out-of-bounds in __acpi_match_device at addr ffff8800001ffd18
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/0day-ci/linux/commits/Hans-de-Goede/ACPI-utils-Add-new...
commit 4d3c75a57e634e201b706628134dfb262379fc31
Author: Hans de Goede <hdegoede(a)redhat.com>
AuthorDate: Fri Apr 7 12:43:44 2017 +0200

ACPI: battery: Add a blacklist with PMIC ACPI HIDs with a native battery driver
On some systems we have a native PMIC driver which provides battery
monitoring, while the ACPI battery driver is broken on these systems
due to bad DSDTs or because we do not support the proprietary and
undocumented ACPI opregions these ACPI battery devices rely on
(e.g. BMOP opregion).
This leads to there being 2 battery power_supply-s registed like this:
~$ acpi
Battery 0: Charging, 84%, 00:49:39 until charged
Battery 1: Unknown, 0%, rate information unavailable
Even if the ACPI battery where to function fine (which on systems
where we have a native PMIC driver it often doesn't) we still do not
want to export the same battery to userspace twice.
This commit adds a blacklist with PMIC ACPI HIDs for which we've a
native battery driver and makes the ACPI battery driver not register
itself when a PMIC on this list is present.

[ACPI: ac] 4d2a8410f1: BUG: KASAN: stack-out-of-bounds in __acpi_match_device at addr ffff880014147da0
by kernel test robot

https://github.com/0day-ci/linux/commits/Hans-de-Goede/ACPI-utils-Add-new...
commit 4d2a8410f1bf8bf5cb7180f11429e02c96dd05a9
Author: Hans de Goede <hdegoede(a)redhat.com>
AuthorDate: Fri Apr 7 12:43:45 2017 +0200

CommitDate: Sat Apr 8 18:07:46 2017 +0800
ACPI: ac: Add a blacklist with PMIC ACPI HIDs with a native charger driver
On some systems we have a native PMIC driver which provides Mains
monitoring, while the ACPI ac driver is broken on these systems
due to bad DSTDs or because we do not support the proprietary and
undocumented ACPI opregions these ACPI battery devices rely on
(e.g. BMOP opregion).
This leads for example to a ADP1 power_supply which reports
itself as always online even if no mains are connected.
This commit adds a blacklist with PMIC ACPI HIDs for which we've a
native charger or extcon driver and makes the ACPI ac driver not
register itself when a PMIC on this list is present.
