		2) Set max number of compression streams
		Compression backend may use up to max_comp_streams compression streams,
		thus allowing up to max_comp_streams concurrent compression operations.
		By default, compression backend uses single compression stream.

		Examples:
		#show max compression streams number
		Regardless the value passed to this attribute, ZRAM will always
		allocate multiple compression streams - one per online CPUs - thus
		allowing several concurrent compression operations. The number of
		allocated compression streams goes down when some of the CPUs
		become offline. There is no single-compression-stream mode anymore,
		unless you are running a UP system or has only 1 CPU online.

		To find out how many streams are currently available:
		cat /sys/block/zram0/max_comp_streams

		#set max compression streams number to 3
		echo 3 > /sys/block/zram0/max_comp_streams

		Note:
		In order to enable compression backend's multi stream support max_comp_streams
		must be initially set to desired concurrency level before ZRAM device
		initialisation. Once the device initialised as a single stream compression
		backend (max_comp_streams equals to 1), you will see error if you try to change
		the value of max_comp_streams because single stream compression backend
		implemented as a special case by lock overhead issue and does not support
		dynamic max_comp_streams. Only multi stream backend supports dynamic
		max_comp_streams adjustment.

		3) Select compression algorithm
		Using comp_algorithm device attribute one can see available and
		currently selected (shown in square brackets) compression algorithms,

		Ramdump Debug Memory

		Debug memory contains necessary information for ramdump to dump
		the memory.This memory is used as a bridge between Android and
		ramdump.

		This memory is used by the modules mentioned below:
		a) Rdtags
		b) Ramdump Memory Descriptors


		Required Properties:
		-compatible: "removed-dma-pool", "qcom,debug_memory"
		-reg: Specifies the physical address of the debug memory region and its size

		Example:
		debug_region: debug_region@57e00000 {
		compatible = "removed-dma-pool", "qcom,debug_memory";
		no-map;
		reg = <0 0x57e00000 0 0x100000>;
		label = "debug_mem";
		};
