[$] Supporting larger block sizes in filesystems

In a combined storage and filesystem session at the 2024Linux Storage,Filesystem, Memory Management, and BPF Summit, Luis Chamberlain led adiscussion on filesystem support for block sizes larger than the usual 4KBpage size, which followed up on discussion from last year. While thesession was meant to look at the intersection of larger block sizeswith atomic block writes that avoid torn(partial) writes (which was also discussed last year), it mostly focused on thefilesystem side. Over time, theblock sizes offered by storage devices have risen from the original512bytes; Chamberlainwanted to discuss filesystem support for block sizes larger than 4KB.
