Subject: [PATCH] lsblk: follow kernel for inverse tree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For multi-path devices kernel defines dependence between the device
and whole-list:

	$ ls /sys/block/dm-0/slaves/
	sdb

but lsblk inserts partition into the tree:

	$ lsblk -s -oNAME,KNAME /dev/dm-1
	mpatha1   dm-1
	└─mpatha  dm-0
	  └─sdb1  sdb1     <--- !
	    └─sdb sdb
