Struct KVmalloc

pub struct KVmalloc;

The kvmalloc kernel allocator.

KVmalloc attempts to allocate memory with Kmalloc first, but falls back to Vmalloc upon failure. This allocator is typically used when the size for the requested allocation is not known and may exceed the capabilities of Kmalloc.

For more details see self.

Trait Implementations

impl Allocator for KVmalloc

const MIN_ALIGN: usize = 8usize

The minimum alignment satisfied by all allocations from this allocator.

unsafe fn realloc( ptr: Option<NonNull<u8>>, layout: Layout, old_layout: Layout, flags: Flags, nid: NumaNode, ) -> Result<NonNull<[u8]>, AllocError>

Re-allocate an existing memory allocation to satisfy the requested layout and a specific NUMA node request to allocate the memory for.

fn alloc( layout: Layout, flags: Flags, nid: NumaNode, ) -> Result<NonNull<[u8]>, AllocError>

Allocate memory based on layout, flags and nid.

unsafe fn free(ptr: NonNull<u8>, layout: Layout)

Free an existing memory allocation.
