| |
2.6.28-stable review patch. If anyone has any objections, please let us know.
------------------
From: Mark Fasheh <mfasheh@suse.com>
(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.
