From 3033342a0b76048e32ce1faebfa85cf8f1aa93b5 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Sun, 24 May 2009 00:09:44 +0900 Subject: nilfs2: remove useless b_low and b_high fields from nilfs_bmap struct This will cut off 16 bytes from the nilfs_bmap struct which is embedded in the on-memory inode of nilfs. The b_high field was never used, and the b_low field stores a constant value which can be determined by whether the inode uses btree for block mapping or not.
