Subject: [PATCH] ext4: ext4_mknod:  always set i_op

While I was looking through the code, I noticed i_op 
is not always initialized, although operations such 
as setattr probably always should be set.


ext4: ext4_mknod:  always set i_op

From: Bernd Schubert <bernd.schubert@...m.fraunhofer.de>

ext4_special_inode_operations have their own ifdef CONFIG_EXT4_FS_XATTR
to mask those methods. And ext4_iget also always sets it, so there is
an inconsistency.
