That was my memory, but I admit I haven't gone diving into the pre-git
linux-history tree to make sure.....

But in any case, the only possible potential conflict would have been
on the XIP patch set, and it doesn't seem to be an issue there.

(BTW, what's the current status on the XIP patch set?  I admit I've
gotten too busy to track its status lately.  There were a bunch of
comments from mm and core vfs folks, but that was a while ago.  What's
still left to be resolved at this point?)
