From 81126650453afa545ce947f5cedbdde1ec78d837 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Tue, 17 Feb 2009 10:58:35 -0500 Subject: jbd2: Add BH_JBDPrivateStart (cherry picked from commit e97fcd95a4778a8caf1980c6c72fdf68185a0838) Add this so that file systems using JBD2 can safely allocate unused b_state bits. In this case, we add it so that Ocfs2 can define a single bit for tracking the validation state of a buffer.
