While the above certainly is true, it doesn't matter whether or not any
out-of-the-tree code will be affected by removing this from the mainline.

What matters is *only* whether or not anyone is going to add anything
depending on it to the mainline any time soon. If that's not the case,
the stuff goes away (and may be added back in the future if need be).

To avoid delaying this indefinitely, let's make a deal as follows.

Unless anyone with some changes targeted at the mainline and depending on the
code in question shows up before the end of the merge window currently under
way, I will queue up the patches from Viresh for 4.16. Then, there will be
8 weeks (or more) of time before the 4.16 merge window opens to drop them if
any new material depending on the code removed by them materializes in the
meantime.

Thanks,
Rafael
