I am concerned that using the term "reserve" here could give the
impression that this memory is then not available for any other use.
It is in fact available for other uses as long as they are movable
allocations. So this memory is available for uses such as process
anonymous memory and page cache, just not for things like kmalloc.
I'm not sure what would be a better term than "reserve", though.
Perhaps we need to add a sentence something like "The reserved memory
is available for use as process memory and page cache when it is not
being used by KVM."
