Hi Ryusuke Konishi, Sorry. The patches passed checkpatch.pl now. Send them again.
Thanks, Li Hong >From bbb2fd5b906dbae1cee759549cb24678e41f824c Mon Sep 17 00:00:00 2001 From: Li Hong <[email protected]> Date: Fri, 2 Apr 2010 17:36:34 +0800 Subject: [PATCH 1/2] nilfs2: Combine nilfs_btree_alloc_path() and nilfs_btree_init_path() nilfs_btree_alloc_path() and nilfs_btree_init_path() are bound into each other tightly. Make them into one procedure to clearify the logic and avoid some misusages.
