jbd2: Add BH_JBDPrivateStart
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. Acked-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
