From afc15a814b9b5879ec361b76d45f68dc3b2cd4c1 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Thu, 17 May 2012 07:46:17 +0300 Subject: UBI: rename struct ubi_scan_info Rename 'struct ubi_scan_info' to 'struct ubi_attach_info'. This is part of the code re-structuring I am trying to do in order to add fastmap in a more logical way. Fastmap can share a lot with scanning, including the attach-time data structures, which all now have "scan" word in the name. Let's get rid of this word.
