From 06894efea706b3cd4ce31e341ec51b4c62c34a86 Mon Sep 17 00:00:00 2001 From: Matias Bjørling Date: Tue, 31 Jan 2017 13:17:17 +0100 Subject: lightnvm: use end_io callback instead of instance MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the lightnvm core had the "gennvm" layer between the device and the target, there was a need for the core to be able to figure out which target it should send an end_io callback to. Leading to a "double" end_io, first for the media manager instance, and then for the target instance. Now that core and gennvm is merged, there is no longer a need for this, and a single end_io callback will do.
