From 6c6de1aa65189c37cc3c9af78da756c06a99899b Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Sat, 30 Apr 2011 18:56:12 +0900 Subject: nilfs2: super root size should change depending on inode size The size of super root structure depends on inode size, so NILFS_SR_BYTES macro should be a function of the inode size. This fixes the issue. Even though a different size value will be written for a possible future filesystem with extended inode, but fortunately this does not break disk format compatibility.
