From 1376e931b75f954057b1547ba25fcba594cef804 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Fri, 13 Nov 2009 16:49:09 +0900 Subject: nilfs2: eliminate nilfs_btnode_get function This removes the obsolete nilfs_btnode_get() function and makes nilfs_btree_get_block() directly call nilfs_btnode_submit_block(). This expansion will provide better opportunity for code optimization.
