From 6d5be9590b5e15124e3c8b319c8d7ce01abcf07d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Javier=20Gonz=C3=A1lez?= Date: Fri, 6 May 2016 20:03:20 +0200 Subject: [PATCH] lightnvm: rename nr_pages to nr_ppas on nvm_rq MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The number of ppas contained on a request is not necessarily the number of pages that it maps to neither on the target nor on the device side. In order to avoid confusion, rename nr_pages to nr_ppas since it is what the variable actually contains.
