From bd8169efae8bdd292675c386010f6b35f0771057 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Sat, 15 Aug 2009 17:22:13 +0900 Subject: nilfs2: add update functions of virtual block address to dat This is a preparation for the successive cleanup ("nilfs2: allow btree to directly call dat operations"). This adds functions bundling a few operations to change an entry of virtual block address on the dat file.
