/**
* EVIOCGMASK - Retrieve current event mask
*
* This ioctl allows user to retrieve the current event mask for specific
* event type. The argument must be of type "struct input_mask" and
* specifies the event type to query, the address of the receive buffer and
* the size of the receive buffer.
*
* The event mask is a per-client mask that specifies which events are
* forwarded to the client. Each event code is represented by a single bit
* in the event mask. If the bit is set, the event is passed to the client
* normally. Otherwise, the event is filtered and will never be queued on
* the client's receive buffer.
*
* Event masks do not affect global state of the input device. They only
* affect the file descriptor they are applied to.
*
* The default event mask for a client has all bits set, i.e. all events
* are forwarded to the client. If the kernel is queried for an unknown
* event type or if the receive buffer is larger than the number of
* event codes known to the kernel, the kernel returns all zeroes for those
* codes.
*
* At maximum, codes_size bytes are copied.
*
* This ioctl may fail with ENODEV in case the file is revoked, EFAULT
* if the receive-buffer points to invalid memory, or EINVAL if the kernel
* does not implement the ioctl.

* EVIOCSMASK - Set event mask
*
* This ioctl is the counterpart to EVIOCGMASK. Instead of receiving the
* current event mask, this changes the client's event mask for a specific
* type. See EVIOCGMASK for a description of event-masks and the
* argument-type.
*
* This ioctl provides full forward compatibility. If the passed event type
* is unknown to the kernel, or if the number of event codes specified in
* the mask is bigger than what is known to the kernel, the ioctl is still
* accepted and applied. However, any unknown codes are left untouched and
* stay cleared. That means, the kernel always filters unknown codes
* regardless of what the client requests. If the new mask doesn't cover
* all known event-codes, all remaining codes are automatically cleared and
* thus filtered.
*
* This ioctl may fail with ENODEV in case the file is revoked. EFAULT is
* returned if the receive-buffer points to invalid memory. EINVAL is returned

/*
* Each virtio-mem device manages a dedicated region in physical address
* space. Each device can belong to a single NUMA node, multiple devices
* for a single NUMA node are possible. A virtio-mem device is like a
* "resizable DIMM" consisting of small memory blocks that can be plugged
* or unplugged. The device driver is responsible for (un)plugging memory
* blocks on demand.
*
* Virtio-mem devices can only operate on their assigned memory region in
* order to (un)plug memory. A device cannot (un)plug memory belonging to
* other devices.
*
* The "region_size" corresponds to the maximum amount of memory that can
* be provided by a device. The "size" corresponds to the amount of memory
* that is currently plugged. "requested_size" corresponds to a request
* from the device to the device driver to (un)plug blocks. The
* device driver should try to (un)plug blocks in order to reach the
* "requested_size". It is impossible to plug more memory than requested.
*
* The "usable_region_size" represents the memory region that can actually
* be used to (un)plug memory. It is always at least as big as the
* "requested_size" and will grow dynamically. It will only shrink when
* explicitly triggered (VIRTIO_MEM_REQ_UNPLUG).
*
* There are no guarantees what will happen if unplugged memory is
* read/written. In general, unplugged memory should not be touched, because
* the resulting action is undefined. There is one exception: without
* VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE, unplugged memory inside the usable
* region can be read, to simplify creation of memory dumps.
*
* It can happen that the device cannot process a request, because it is
* busy. The device driver has to retry later.
*
* Usually, during system resets all memory will get unplugged, so the
* device driver can start with a clean state. However, in specific
* scenarios (if the device is busy) it can happen that the device still
* has memory plugged. The device driver can request to unplug all memory
* (VIRTIO_MEM_REQ_UNPLUG) - which might take a while to succeed if the
* device is busy.

/*
* This structure provides a vDSO-style clock to VM guests, exposing the
* relationship (or lack thereof) between the CPU clock (TSC, timebase, arch
* counter, etc.) and real time. It is designed to address the problem of
* live migration, which other clock enlightenments do not.
*
* When a guest is live migrated, this affects the clock in two ways.
*
* First, even between identical hosts the actual frequency of the underlying
* counter will change within the tolerances of its specification (typically
* ±50PPM, or 4 seconds a day). This frequency also varies over time on the
* same host, but can be tracked by NTP as it generally varies slowly. With
* live migration there is a step change in the frequency, with no warning.
*
* Second, there may be a step change in the value of the counter itself, as
* its accuracy is limited by the precision of the NTP synchronization on the
* source and destination hosts.
*
* So any calibration (NTP, PTP, etc.) which the guest has done on the source
* host before migration is invalid, and needs to be redone on the new host.
*
* In its most basic mode, this structure provides only an indication to the
* guest that live migration has occurred. This allows the guest to know that
* its clock is invalid and take remedial action. For applications that need
* reliable accurate timestamps (e.g. distributed databases), the structure
* can be mapped all the way to userspace. This allows the application to see
* directly for itself that the clock is disrupted and take appropriate
* action, even when using a vDSO-style method to get the time instead of a
* system call.
*
* In its more advanced mode. this structure can also be used to expose the
* precise relationship of the CPU counter to real time, as calibrated by the
* host. This means that userspace applications can have accurate time
* immediately after live migration, rather than having to pause operations
* and wait for NTP to recover. This mode does, of course, rely on the
* counter being reliable and consistent across CPUs.
*
* Note that this must be true UTC, never with smeared leap seconds. If a
* guest wishes to construct a smeared clock, it can do so. Presenting a
* smeared clock through this interface would be problematic because it
* actually messes with the apparent counter *period*. A linear smearing
* of 1 ms per second would effectively tweak the counter period by 1000PPM
* at the start/end of the smearing period, while a sinusoidal smear would
* basically be impossible to represent.
*
* This structure is offered with the intent that it be adopted into the
* nascent virtio-rtc standard, as a virtio-rtc that does not address the live
* migration problem seems a little less than fit for purpose. For that
* reason, certain fields use precisely the same numeric definitions as in
* the virtio-rtc proposal. The structure can also be exposed through an ACPI
* device with the CID "VMCLOCK", modelled on the "VMGENID" device except for
* the fact that it uses a real _CRS to convey the address of the structure
* (which should be a full page, to allow for mapping directly to userspace).
