Cool.

I've split the original patch on 3 pieces:
1. VFS: move inode_lock into sync_sb_inodes
2. VFS: export sync_sb_inodes
3. VFS: introduce sync_inodes superblock operation

The first 2 are exactly what UBIFS also needs. The third one is only
needed for Reiser4. The patches are attached.

I am not sure this is the best way to split. The second patch could
just export sync_sb_inodes() without renaming it to
generic_sync_sb_inodes(). But in this case we would have more complex
third patch and more dependencies between reiser4 and ubifs. What is
better?
