I hadn't gotten around to applying them to my testing tree. 
Worth noting that of the dozens of oopses I've seen the last few days
I think I only saw this one once.

(Though I've narrowed my testing scope right now to try and tickle
 those fs/namei.c bugs, so it could just be that I'm not exercising
 the codepaths that caused the ipc bug)
