From dab4b4d2f915a65022343012a795f4ae4ae7e83c Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Thu, 24 Jul 2008 14:52:45 +0300 Subject: UBIFS: align inode data to eight UBIFS aligns node lengths to 8, so budgeting has to do the same. Well, direntry, inode, and page budgets are already aligned, but not inode data budget (e.g., data in special devices or symlinks). Do this for inode data as well. Also, add corresponding debugging checks.
