Understand the kernel source tree, process scheduler, virtual memory subsystem, and how to navigate and cross-reference kernel code effectively.

Explore slab allocators, page allocation, vmalloc, memory cgroups, and write a custom allocator for a specific workload.

Implement a simple in-kernel filesystem using the VFS layer, understand inodes, dentries, superblocks, and the page cache.

Write eBPF programs in C for tracing, networking, and security, compile with clang, and load them with libbpf or bpftool.
