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

(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)
