Function try_mmap_contiguous_metadata_space

source 
pub(super) fn try_mmap_contiguous_metadata_space(
    start: Address,
    size: usize,
    spec: &SideMetadataSpec,
    no_reserve: bool,
    anno: &MmapAnnotation<'_>,
) -> Result<usize>
Expand description

Tries to mmap the metadata space (spec) for the specified data address range (start and size). Setting no_reserve to true means the function will only map address range, without reserving swap-space/physical memory. Returns the size in bytes that gets mmapped in the function if success.
