In the current state, the perf_domain struct is fully defined only when
CONFIG_ENERGY_MODEL=y. Since we need to write code that compiles both

Hi,
making this holder of mmap_sem killable was for the reasons of /proc/...
diagnostics was an idea I was pondeering too. However, I think the
approach of pretending we read 0 bytes is not correct. The API would IMO
need to be extended to allow pass a result such as EINTR to the end
caller.
Why do
Do not stuck forever if something wrong.

The cgroup testing relys on the root cgroup's subtree_control setting,
If the 'memory' controller isn't set, some test cases will be failed
as following:
$sudo ./test_core
not ok 1 test_cgcore_internal_process_constraint
ok 2 test_cgcore_top_down_constraint_enable
not ok 3 test_cgcore_top_down_co
The cgroup testing relys on the root cgroup's subtree_control setting,

as following:
$ sudo ./test_memcontrol

The test_core will skip the
test_cgcore_no_internal_process_constraint_on_threads test case if the
'cpu' controller missing in root's subtree_control. In fact we need to
set the 'cpu' in subtree_control, then the testing is meaningful.

The problem is that on 64bit systems then we don't clear the higher
bits of the "pending" variable. So when we do:
ack = pending & ~BIT(STMFX_REG_IRQ_SRC_EN_GPIO);
if (ack) {
the if (ack) condition relies on uninitialized data. The fix it that

The limit here is supposed to be how much of the page is left, but it's
just using PAGE_SIZE as the limit.
The other thing to remember is that snprintf() returns the number of
bytes which would have been copied if we had had enough room. So that
means that if we run out of space then this code wo

Utilization clamping allows to clamp the CPU's utilization within a
[util_min, util_max] range, depending on the set of RUNNABLE tasks on
that CPU. Each task references two "clamp buckets" defining its minimum
and maximum (util_{min,max}) utilization "clamp values". A CPU's clamp
bucket is active i
There may be no cooling device on system, or there are no enough
cooling devices for each thermal zone in multiple thermal zone
cases since cooling devices can't be shared.
So make this property optional to remove such limitations.
