Hello Dimitry,
Since I am only responding to you and not to a list where others

OK.

Your request cannot be satisfied since the MEMTEST option is only
available for x86. However, I suspect that's all you really care about.

So the feature won't be available on amd64?
Just x86 is a bit disappointing but certainly better

Having a feature enabled in the Debian kernel (at release time) is a
promise to continue supporting it for the period in which that release

With the latter you have a test case to determine if your
RAM is bad (or not). With the memtest kernel option memory is tested
before it's given out to kmalloc. So it is able in some cases to just
not give out bad parts of RAM allowing to use RAM that is a bit broken.

Indeed. In this case we're talking about 130 lines of source code (3 KB), see

Binary size overhead is really negligible.
No opinion on that from me. It does seem a shame that many kinds of

Are we censoring certain Linux Kernel features because they are not good

If so,

I very much disagree, unless this wishlist will be closed by enabling the
feature requested.
This *useful* feature has been

This tiny feature is only activated with boot-time parameter so it is harmless,
but powerful for those who want to use it.
