[$] Moving the kernel to large block sizes

Using larger block sizes in the kernel for I/O is a recurring topic instorage and block-layer circles. The topic came up in discussions at the Linux Storage, Filesystem, Memory-Management and BPF Summit (LSFMM)back in May. One of the participants in those discussions, Hannes Reinecke, gavea talk at Open Source Summit Europe 2023 with an overview of the reasonsbehind using larger blocks for I/O, the current status of that work, andwhere it all might lead from here.
