Constant mmtk::util::heap::layout::vm_layout_constants::LOG_BYTES_IN_CHUNK

pub const LOG_BYTES_IN_CHUNK: usize = 22;

log_2 of the coarsest unit of address space allocation.

In the 32-bit VM layout, this determines the granularity of allocation in a discontigouous space. In the 64-bit layout, this determines the growth factor of the large contiguous spaces that we provide.
