	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.

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

The layout of the formatted block device:

consideration the effect of compiler optimisations which may occur

when tail-calls are used and marked with the noreturn GCC attribute.

Probed Pointers from BPF / tracing

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

::

	%pks	kernel string

	%pus	user string

The ``k`` and ``u`` specifiers are used for printing prior probed memory from

either kernel memory (k) or user memory (u). The subsequent ``s`` specifier

results in printing a string. For direct use in regular vsnprintf() the (k)

and (u) annotation is ignored, however, when used out of BPF's bpf_trace_printk(),

for example, it reads the memory it is pointing to without faulting.

- compatible :

	- "fsl,vf610-edma" for eDMA used similar to that on Vybrid vf610 SoC

	- "fsl,imx7ulp-edma" for eDMA2 used similar to that on i.mx7ulp

	- "fsl,fsl,ls1028a-edma" for eDMA used similar to that on Vybrid vf610 SoC

	- "fsl,ls1028a-edma" followed by "fsl,vf610-edma" for eDMA used on the

	  LS1028A SoC.

- reg : Specifies base physical address(s) and size of the eDMA registers.

	The 1st region is eDMA control register's address and size.

	The 2nd and the 3rd regions are programmable channel multiplexing
