Maciej W. Rozycki worked out that it depends on commit 27e28e8ec47a

[PATCH 3.16 00/76] 3.16.56-rc1 review
This is the start of the stable review cycle for the 3.16.56 release.
There are 76 patches in this series, which will be posted as responses
to this one. If anyone has any issues with these being applied, please
let me know.
Responses should be made by Wed Mar 14 12:00:00 UTC 2018.
Anything received after that time might be too late.
All the patches have also been committed to the linux-3.16.y-rc branch of
https://git.kernel.org/pub/scm/linux/kernel/git/bwh/linux-stable-rc.git .
A shortlog and diffstat can be found below.
