I took both patches from linux-trace.git/ftrace/urgent.

So, both patches were updated and especially 2/2 misses...

- Tested-by's
- Reference of 2/2 to 1/2
- CC: stable v3.17+/v3.18+ ? (1/2 has a hint for backporting in case
of 3.17+ which is BTW EOL, not sure if there are main distros
supporting linux-3.17.y)

BTW, do you happen to know if there is a someting like a
"Requires-tag" or "Precondition-tag" (for example the Fixes-tag is
very helpful)?
AFAICS people place such information into the commit-message.
I have seen "References:" but this is more to point to a
bug-tracking-system (BTS).

EXAMPLE:

commit 63b03e2d2477586440741677ecac45bcf28d7b1
"mutex: Always clear owner field upon mutex_unlock()"

References: https://bugs.freedesktop.org/show_bug.cgi?id=87955

Maybe ask godfather of SubmittingPatches greg-kh?
