[$] Moving the kernel to large block sizes

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 https://lwn.net/Articles/933437/
 
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.
