Summary
fs/9p: fix uninitialized values during inode evict
Details

In the Linux kernel, the following vulnerability has been resolved:

fs/9p: fix uninitialized values during inode evict

If an iget fails due to not being able to retrieve information from the server then the inode structure is only partially initialized. When the inode gets evicted, references to uninitialized structures (like fscache cookies) were being made.

This patch checks for a bad_inode before doing anything other than clearing the inode from the cache. Since the inode is bad, it shouldn't have any state associated with it that needs to be written back (and there really isn't a way to complete those anyways).
