Using larger block sizes in the kernel for I/O is a recurring topic in
storage 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, gave
a talk at Open Source Summit Europe 2023 with an overview of the reasons
behind using larger blocks for I/O, the current status of that work, and
where it all might lead from here.
