Well, I didn't miss that one either (see commit cb787f4ac0c2:
"[tree-wide] finally take no_llseek out") but yes, it's probably
better to mark those kinds of things very obviously too (and a
'[PATCH-for-linus]' like subject line is probably good there too).

And hey, people will forget, and I'll - mostly - figure it out anyway,
so it's not like this is a big worry. Maybe if you notice that I
missed something, you can make sure that the re-send has a big neon
sign for me.
