[Ocfs2-devel] [BUG] can not chmod to 777

[Kurt Hackel]

Definitely could be.  Dynamic resizing is not much harder than
dynamically changing the root inode, especially since you have the
advantage of locking out all allocs by taking the global bitmap lock.  
Using the same method, the release lock would be the signal for other
nodes to resize their in-memory bitmaps.  Wouldn't be too difficult.
