From 8362c2608ba1be635ffa22a256dfcfe51c6238cc Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Fri, 4 Oct 2024 17:41:13 +0200 Subject: rust: alloc: implement `KVmalloc` allocator Implement `Allocator` for `KVmalloc`, an `Allocator` that tries to allocate memory with `kmalloc` first and, on failure, falls back to `vmalloc`. All memory allocations made with `KVmalloc` end up in `kvrealloc_noprof()`; all frees in `kvfree()`.
