That and the previous commit appear to be sufficient, though they
needed some minor changes. Please can you test whether the attached
patches work, following the procedure at
<https://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official>.

I tested these patches on Jessie and they seem to work. Methodology: I spun up an 3.16.7-ckt20-1+deb8u3 image in GCE, made sure https://hub.docker.com/r/akihirosuda/test18180/ failed as expected. I built a 3.16.7-ckt20-1+deb8u3 kernel with those patches quilted in and ran the same image:

zml@jessie:~$ sudo docker run -it --rm akihirosuda/test18180
[INFO] Checking whether hitting docker#18180.
....................................................................................................
[INFO] OK. not hitting docker#18180.
[INFO] Checking whether sendfile(2) is killable.
[INFO] If the container hangs up here, you are still facing the bug that linux@296291cd tried to fix.
/test.sh: line 22:  3308 Killed                  /sendfile-test
zml@jessie:~$

I think we're golden. (Container is not hung, both the original bug and the new bug are fixed.)
