From 25b8d7ded0e4579bf152882249abfd351e65a17d Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Sat, 10 Jul 2010 16:50:41 +0900 Subject: nilfs2: get rid of private conversion macros on bmap key and pointer Will remove nilfs_bmap_key_to_dkey(), nilfs_bmap_dkey_to_key(), nilfs_bmap_ptr_to_dptr(), and nilfs_bmap_dptr_to_ptr() for simplicity.
