Some questions about the standard content

[Joe.MacDonald@xxxxxxxxxxxxx (Joe MacDonald)]

Hi Dongyu,

I don't know if this has been answered on the list or not yet, I didn't
see a follow-up.  Sorry about the delay.

This is an old requirement that the CGL workgroup had determined is now
present in all modern linux kernels and therefore, as you have probably
now seen, has been deprecated in CGL 5.0.  For the purposes of
completing your CGL 4.0 registration you can simply claim that this is
implemented by the linux kernel itself so long as you're using any
relatively recent (2.6-based) linux kernel.  Certainly any mainline
kernel in the last four years would qualify unless you have specific
patches that are modifying how memory is allocated to processes.

This is typically implemented via tmpfs, which is also present in modern
kernels, though you are free to implement it in some other way that also
meets the requirement description.  The key point here is something that
behaves like a filesystem but can be resized as necessary and is not
backed by physical media.

I hope that helps.

I think we've covered this, but in short you can only claim features
that are currently released and supported in your product.  You are, of
course, free to amend your registration after the initial registration
is complete and we can re-evaluate it.
