Ryusuke Konishi	7cde31d7d6	nilfs2: remove nilfs_btree_operations from btree mapping ... will remove indirect function calls using nilfs_btree_operations table. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>	2009-06-10 23:41:11 +09:00
Ryusuke Konishi	3033342a0b	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.

Koji Sato	17c76b0104	nilfs2: B-tree based block mapping ... This adds declarations and functions of NILFS2 B-tree. Two variants are integrated in the NILFS2 B-tree. The B-tree for the most files points to the child nodes or data blocks with virtual block addresses, whereas the B-tree of the DAT uses actual block addresses.
