From 6732c7401035c8464fd4ab5ff2e1bf86e5fcd74c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Matias=20Bj=C3=B8rling?= Date: Wed, 15 Feb 2017 16:25:33 +0100 Subject: lightnvm: set default lun range when no luns are specified MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The create target ioctl takes a lun begin and lun end parameter, which defines the range of luns to initialize a target with. If the user does not set the parameters, it default to only using lun 0. Instead, defaults to use all luns in the OCSSD, as it is the usual behaviour users want.
