Subject[PATCH] bad_inode: add missing i_op initializers for fileattr_get/_set
Date
Let's bring inode_operations in sync for bad_inode_ops.
Some of the reasons are listed here [1]. But mostly it is
just for completeness sake I think.

This patch also removes some of the whitespaces at the end of line
which is due to my editor config settings for kernel work.
