	space-efficient. If this option is not present, large padding is

	used - that is for compatibility with older kernels.

The journal mode (D/J), buffer_sectors, journal_watermark, commit_time can

be changed when reloading the target (load an inactive table and swap the

tables with suspend and resume). The other arguments should not be changed

when reloading the target because the layout of disk data depend on them

and the reloaded target would be non-functional.

allow_discards

	Allow block discard requests (a.k.a. TRIM) for the integrity device.

	Discards are only allowed to devices using internal hash.

Version 1 of the Activity Monitors architecture implements a counter group

of four fixed and architecturally defined 64-bit event counters.

- CPU cycle counter: increments at the frequency of the CPU.

- Constant counter: increments at the fixed frequency of the system

  clock.

Firmware (code running at higher exception levels, e.g. arm-tf) support is

needed to:

- Enable access for lower exception levels (EL2 and EL1) to the AMU

  registers.

- Enable the counters. If not enabled these will read as 0.

The fixed counters of AMUv1 are accessible though the following system

register definitions:

- SYS_AMEVCNTR0_CORE_EL0

- SYS_AMEVCNTR0_CONST_EL0

- SYS_AMEVCNTR0_INST_RET_EL0

----------------

Currently, access from userspace to the AMU registers is disabled due to:

- Security reasons: they might expose information about code executed in

  secure mode.

- Purpose: AMU counters are intended for system management use.

Currently, access from userspace (EL0) and kernelspace (EL1) on the KVM

guest side is disabled due to:

- Security reasons: they might expose information about code executed

  by other guests or the host.
