ext4: Avoid updating the inode table bh twice in no journal mode
This is a cleanup of commit 91ac6f4. Since ext4_mark_inode_dirty() has already called ext4_mark_iloc_dirty(), which in turn calls ext4_do_update_inode(), it's not necessary to have ext4_write_inode() call ext4_do_update_inode() in no journal mode. Indeed, it would be duplicated work. Reviewed-by: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Frank Mayhar <fmayhar@google.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
