ring_buffer: Fix more races when terminating the producer in the benchmark
The commit b44754d8262d3aab8 ("ring_buffer: Allow to exit the ring
buffer benchmark immediately") added a hack into ring_buffer_producer()
that set @kill_test when kthread_should_stop() returned true. It improved
the situation a lot. It stopped the kthread in most cases because
the producer spent most of the time in the patched while cycle.
But there are still few possible races when kthread_should_stop()
is set outside of the cycle. Then we do not set @kill_test and
some other checks pass.
This patch adds a better fix. It renames @test_kill/TEST_KILL() into
a better descriptive @test_error/TEST_ERROR(). Also it introduces
break_test() function that checks for both @test_error and
kthread_should_stop().
The new function is used in the producer when the check for @test_error
is not enough. It is not used in the consumer because its state
is manipulated by the producer via the "reader_finish" variable.
Also we add a missing check into ring_buffer_producer_thread()
between setting TASK_INTERRUPTIBLE and calling schedule_timeout().
Otherwise, we might miss a wakeup from kthread_stop().
ring_buffer_producer()
# CPU3 removes the module <--- difference from
# and stops producer <--- the 1st scenario
if (kthread_should_stop())
kill_test = 1;
ring_buffer_consumer();
while (!reader_finish &&
!kill_test)
# kill_test == 1 => we never go
# into the top level while()
reader_finish = 0;
complete(&read_done);
# producer still in the middle of
# do-while cycle
if (consumer && !(cnt % wakeup_interval))
wake_up_process(consumer);
# spurious wakeup
while (!reader_finish &&
!kill_test)
# leaving because kill_test == 1
reader_finish = 0;
complete(&read_done);
BANG: We are in the same "bang" situations as in the 1st scenario.
Root of the problem:
--------------------
ring_buffer_consumer() must complete "read_done" only when "reader_finish"
variable is set. It must not be skipped due to other conditions.
Note that we still must keep the check for "reader_finish" in a loop
because there might be spurious wakeups as described in the
above scenarios.
Solution:
----------
The top level cycle in ring_buffer_consumer() will finish only when
"reader_finish" is set. The data will be read in "while-do" cycle
so that they are not read after an error (kill_test == 1)
or a spurious wake up.
In addition, "reader_finish" is manipulated by the producer thread.
Therefore we add READ_ONCE() to make sure that the fresh value is
read in each cycle. Also we add the corresponding barrier
to synchronize the sleep check.
Next we set the state back to TASK_RUNNING for the situation where we
did not sleep.
Just from paranoid reasons, we initialize both completions statically.
This is safer, in case there are other races that we are unaware of.
As a side effect we could remove the memory barrier from
ring_buffer_producer_thread(). IMHO, this was the reason for
the barrier. ring_buffer_reset() uses spin locks that should
provide the needed memory barrier for using the buffer.

vfio: Include No-IOMMU mode
There is really no way to safely give a user full access to a DMA
capable device without an IOMMU to protect the host system. There is
also no way to provide DMA translation, for use cases such as device
assignment to virtual machines. However, there are still those users
that want userspace drivers even under those conditions. The UIO
driver exists for this use case, but does not provide the degree of
device access and programming that VFIO has. In an effort to avoid
code duplication, this introduces a No-IOMMU mode for VFIO.
This mode requires building VFIO with CONFIG_VFIO_NOIOMMU and enabling
the "enable_unsafe_noiommu_mode" option on the vfio driver. This
should make it very clear that this mode is not safe. Additionally,
CAP_SYS_RAWIO privileges are necessary to work with groups and
containers using this mode. Groups making use of this support are
named /dev/vfio/noiommu-$GROUP and can only make use of the special
VFIO_NOIOMMU_IOMMU for the container. Use of this mode, specifically
binding a device without a native IOMMU group to a VFIO bus driver
will taint the kernel and should therefore not be considered
supported. This patch includes no-iommu support for the vfio-pci bus
driver only.

thermal: rockchip: support the sleep pinctrl state to avoid glitches in s2r
When we come out of system suspend state (S3) the tsadc will have been
reset and back at its default state. While reprogramming the tsadc
it's possible that we'll glitch the output and unintentionally cause
the "over temperature" GPIO to be asserted. Since the over
temperature GPIO is often hooked up to something that will cause a
reboot or shutdown in hardware, this glitch can be catastrophic on
some boards.
We'll add support for selecting the "sleep" pinctrl state at suspend
time. Boards can use this to effectively disable the tsadc at suspend
time and avoid glitches when the system is resumed.

dt-bindings: rockchip-thermal: Add the pinctrl states in this document
The "init" pinctrl is defined we'll set
pinctrl to this state before probe and then "default" after probe.
Add the "init" and "sleep" pinctrl as the OTP gpio state, since we need
switch the pin to gpio state before the TSADC controller is reset.
AFAIK, the TSADC controller is reset, the tshut polarity will be
a *low* signal in a short period of time for some devices.
Says:
The TSADC get the temperature on rockchip thermal.
If T(current temperature) < (setting temperature), the OTP output the
*high* signal.
If T(current temperature) > (setting temperature), the OTP output the
*low* Signal.
In some cases, the OTP pin is connected to the PMIC, maybe the
PMIC can accept the reset response time to avoid this issue.
In other words, the system will be always reboot if we make the

lightnvm: refactor phys addrs type to u64
For cases where CONFIG_LBDAF is not set. The struct ppa_addr exceeds its
type on 32 bit architectures. ppa_addr requires a 64bit integer to hold

replaces the sector_t usages with u64 for physical addresses.
This driver uses 'struct timeval' which we are trying to remove since
32 bit time types will break in the year 2038 by replacing it with
ktime_t.
This patch changes do_gettimeofday() to ktime_get() because
ktime_get() returns a ktime_t while do_gettimeofday() returns struct

blk-mq: avoid excessive boot delays with large lun counts
Hi,
Zhangqing Luo reported long boot times on a system with thousands of
LUNs when scsi-mq was enabled. He narrowed the problem down to
blk_mq_add_queue_tag_set, where every queue is frozen in order to set
the BLK_MQ_F_TAG_SHARED flag. Each added device will freeze all queues
added before it in sequence, which involves waiting for an RCU grace
period for each one. We don't need to do this. After the second queue
is added, only new queues need to be initialized with the shared tag.
We can do that by percolating the flag up to the blk_mq_tag_set, and
updating the newly added queue's hctxs if the flag is set.
This problem was introduced by commit 0d2602ca30e41 (blk-mq: improve

s390/cio: de-duplicate subchannel validation
cio_validate_io_subchannel() and cio_validate_msg_subchannel() are
identical, as the called functions already take care about the
differences between subchannel types.
Just inline the code into the only user,
cio_validate_subchannel(), instead.

Depending on the gcc version we can use builtin_bswap instead of
architecture functions. Doing so is better than the inline assembly
version of load reverse for two reasons:
- the sequence of load reversed, apply constant mask, save reversed can
be optimized to load, apply reversed mask, save
- builtins are slightly better to optimize e.g. gcc instruction
scheduler cannot optimize grouping on inline assemblies.
To enable set we have to ARCH_USE_BUILTIN_BSWAP.

s390/dasd: fix disconnected device with valid path mask
Path verification is either done via dasd_eckd_read_conf() which is
triggered during online processing and resume or via
do_path_verification_work() which is triggered after path events.
The dasd_eckd_read_conf() version added paths unconditionally and did
not check if the path mask was empty. This led to devices having the
disconnected stop flag set but a valid path mask. So they where not
working although they had paths validated successfully. After a resume
this state could even not be solved with additional paths added.
Fix by checking for an empty path mask in dasd_eckd_read_conf() and
clearing the device stop bits for a newly added channel path.

s390/dasd: fix invalid PAV assignment after suspend/resume
For a valid PAV assignment the DASD driver needs to notice possibly
changed configuration data. Thus the failing of read configuration
data should also fail the device restore to prevent invalid PAV
assignment. The failed device may get restored after additional paths
get available later on.
If the restore fails after the device was added to the lcu alias
handling it needs to be removed from the alias handling before exiting
the restore function.

s390/dasd: fix double free in dasd_eckd_read_conf
The configuration data is stored per path and also the first valid
configuration data per device. When dasd_eckd_read_conf is called
again after a path got lost the device configuration data is cleared
but possibly not the per path configuration data. This might lead to a
double free when the lost path gets operational again.
Fix by clearing all per path configuration data when the first valid
configuration data is received and stored.
