From 999b204383ffb4eee1467604a935ed3a670c460e Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Thu, 9 Aug 2018 16:17:43 +0200 Subject: [PATCH] dm: print the index of the device when dumping the dm tree Command "dm tree" dumps the devices with class, driver, name information. Add the index of the device in the class too, because the information is useful for the bind/unbind commands.
