From 116f7d4a21fe450efc652c4850eb27cda36c9db0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Javier=20Gonz=C3=A1lez?= Date: Fri, 6 May 2016 20:03:21 +0200 Subject: [PATCH] lightnvm: reserved space calculation incorrect MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The nvm_dev->max_pages_per_blk variable was removed in favor of the new nvm->sec_per_blk variable. The ->max_pages_per_blk variable was still used in rrpc_capacity, reporting the reserved capacity to zero. Replace with ->sec_per_blk to calculate the reserved area again.
