In this video, we explore Linux kernel memory allocation mechanisms used in device driver development.
We discuss how kmalloc, kzalloc, and vmalloc work, when to use each one, and how GFP flags affect memory allocation behavior.
We also introduce the slab allocator, explain how it manages small kernel objects efficiently,
and demonstrate direct slab cache creation using example code.
Finally, we look at real kernel outputs using "/proc/meminfo" and "/proc/slabinfo",
and explain SLUB cache merging behavior.
