It is pointless to calculate the swap ratio when there is only
one swap device in the group. Moreover the existing code would
result in a spinlock recursion because of not taking this into
consideration. Interestingly, this check is already performed
in swap_ratio_slow by this piece of code
if (&(*si)->avail_list == plist_last(&swap_avail_head)) {
/* just to make skip work */
n = *si;
ret = -ENODEV;
goto skip;
}
But there is window where we drop the swap_avail_lock before
invoking swap_ratio() and take it back again in swap_ratio_slow.
In this period the si can get removed from swap_avail_head,
resulting in the failure of above logic. So recheck again.
Similarly, bail out from swap_ratio() if the sysctl is disabled,
and thus avoiding overhead of taking unnecessary locks.

It is observed that sometimes multiple tasks get blocked in

(__slab_alloc) from [<c01f1a6c>]
In one such instance, zone_page_state(zone, NR_ISOLATED_FILE)
had returned 14, zone_page_state(zone, NR_INACTIVE_FILE)
returned 92, and the gfp_flag was GFP_KERNEL which resulted
in too_many_isolated to return true. But one of the CPU pageset
vmstat diff had NR_ISOLATED_FILE as -14. As there weren't any more
update to per cpu pageset, the threshold wasn't met, and the
tasks were blocked in the congestion wait.
This patch uses zone_page_state_snapshot instead, but restricts
its usage to avoid performance penalty.

This module provides support to userspace entity for hotplugging
and setting cpufreq policy min/max limits. It can also detect
cpu/io workload and notify userspace via sysfs nodes.
A userspace entity can specify a CPU mask and the number of CPUs
it wants online within that mask and this module will try to make
a best effort to keep those many CPUs online. Userspace can also
specify the min and max limits on CPUs instead of writing to the
scaling_min/max nodes from sysfs so that if any CPU is offline
this module maintains a vote for it which is applied
once the CPU comes back online.
A userspace entity can also set threshold value in sysfs nodes of
this module for cpu/io workload detection and this module can notify
userspace entity when that crietia is met via sysfs nodes.

2. In P2P listen, when listen timer expires and user space calls

Added support for the P2P_DEVICE virtual interface. This interface
is intended for P2P management operations such as discovery and
GO negotiation. Normally it is implemented by drivers to allow
a separate interface for P2P management with its own MAC address,
but for 11ad drivers it is needed to support P2P search, since it
cannot otherwise be separated from normal scan.
Since we only support a single interface/MAC address, we can't
easily separate between primary and P2P_DEVICE interfaces.
For example when a management packet arrives we can't tell for
which interface it is intended. To work around this, we store
a pointer to the interface where the last "radio operation" was
triggered such as scan or remain on channel, and we forward
management packets and scan results to this interface.

Related threads in a group could execute on different CPUs and hence
present a split-demand picture to cpufreq governor. IOW the governor
fails to see the net cpu demand of all related threads in a given
window if the threads's execution were to be split across CPUs. That
could result in sub-optimal frequency chosen in comparison to the
ideal frequency at which the aggregate work (taken up by related
threads) needs to be run.
This patch aggregates cpu execution stats in a window for all related
threads in a group. This helps present cpu busy time to governor as if
all related threads were part of the same thread and thus help select
the right frequency required by related threads. This aggregation
is done per-cluster.

The POWER_SUPPLY_PROP_PD_ACTIVE property is intended to be a flag
set whenever the PD PHY is in use. But this includes attempts to
establish communication, which may involve trying to perform a hard
reset to see if the port partner responds. Thus updating the
psy_desc.type field to 'USB_PD' right when PD_ACTIVE=1 is premature
as the port partner may not be PD-capable and it could be un-set.
Instead allow the PD driver to directly update POWER_SUPPLY_PROP_TYPE
only after it is sure PD communication has succeeded.
