ext4: dynamically allocate the jbd2_inode in ext4_inode_info as necessary
Replace the jbd2_inode structure (which is 48 bytes) with a pointer and only allocate the jbd2_inode when it is needed --- that is, when the file system has a journal present and the inode has been opened for writing. This allows us to further slim down the ext4_inode_info structure. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
