From 05a3cb7dcec5a15ed9b18a5317ba2075355c7547 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Sun, 20 May 2012 21:14:22 +0300 Subject: [PATCH] UBI: introduce UBI_ALL constant Joel will use it in his 'ubi_flush()' extention to specify all eraseblocks. Also amend the comment for UBI_UNKNOWN - it is used beyond attaching info structure now.
