The changes and conflicts are definitely still there (now upstream),
I'm not sure what made you not see them.  But thanks for the note, I
compared my end result with linux-next to verify.

My resolution is different from Stephen's. All my non-x86-64 FS_IOC_*
cases just do "goto found_handler", because the compat case is
identical for the native case outside of the special x86-64 alignment
behavior, and I think that's what Arnd meant to happen.

There was some other minor difference too, but it's also possible I
could have messed up, so cc'ing Stephen and Arnd on this just in case
they have comments.
