From 948cfb219bbbc3c8e1b10a671ca88219fa42a052 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Wed, 20 Aug 2008 11:56:33 +0300 Subject: UBIFS: add a print, fix comments and more minor stuff This commit adds a reserved pool size print and tweaks the prints to make them look nicer. It also fixes and cleans-up some comments. Additionally, it deletes some blank lines to make the code look a little nicer. In other words, nothing essential.
