Before, only control_reset() was implemented. However, the reset core only
invokes control_reset() once in its lifetime. Because we need it to invoke
control_reset() again after resume out of S2 or S3, we have switched to
putting the reset functionality into the control_deassert() method and

This driver may use one of two resets controllers. Keep them in separate
variables to keep things simple. The reset controller "rescal" is shared
between the AHCI driver and the PCIe driver for the BrcmSTB 7216 chip. Use

Implementation of support for parameterized testing in KUnit.
This approach requires the creation of a test case using the
KUNIT_CASE_PARAM macro that accepts a generator function as input.
This generator function should return the next parameter given the
previous parameter in parameterized tests.
Modify fs/ext4/inode-test.c to use the parameterized testing
feature of KUnit.

So as it stands, it does not work at all. I will continue to check
another machine, and see if I can get something working.
On the MacBookAir3,1 the situation is somewhat better.
The first three tree positions result in zero failures and 10 reads per
second. The fourth yields zero failues and

Simply refer to what was the bonding "master" as the "bond" or bonding

The bonding driver's use of master and slave, while largely understood
in technical circles, poses a barrier for inclusion to some potential
members of the development and user community, due to the historical
context of masters and slaves, particularly in the United States. This
is a first full pa
Swap in port/bond terminology where appropriate, leaving all legacy sysfs
and procfs interface mentions in place, but marked as deprecated.
Additionally, add more netlink/iproute2 documentation, and note that this
is the preferred method of interfacing with the bonding driver. While
we're at it, al
The intention is to reuse "port" in place of "slave" in the bonding driver
after making this change, as port is consistent with the bridge and team
drivers, and allows us to remove socially problematic language from the
bonding driver.

Now that use of "slave" has been replaced by "port", rename this file too.

The kernel cmdline reboot= option offers some sort of control
on how the reboot is issued.
Add handles in sysfs to allow setting these reboot options, so they
can be changed when the system is booted, other than at boot time.
The handlers are under /kernel/reboot, can be read

When the AMD QoS feature CDP(code and data prioritization) is enabled
or disabled, the CDP bit in MSR _0C81 is written on one of the
cpus in L3 domain(core complex). That is not correct. The CDP bit needs
to be updated all the logical cpus in the domain.
This was not spelled out clearly in the

A VCPU of a VM can allocate couple of pages which can be mmap'ed by the
user space application. At the moment this memory is not charged to the
memcg of the VMM. On a large machine running large number of VMs or
small number of VMs having large number of VCPUs, this unaccounted
memory can be very s

It's hard to have some tests to be supposed to work under heavy
memory pressure(e.g., injecting some memory hogger) because
out-of-memory killer easily kicks out one of processes so system
is broken or system loses the memory pressure state since it has
plenty of free memory soon so.
Even though we
