[$] Supporting larger block sizes in filesystems

Date:
Wed, 22 May 2024 20:10:22 +0000

Description:
In a 
combined storage and filesystem session at the 2024 Linux Storage,
Filesystem, Memory Management, and BPF Summit , Luis Chamberlain led a
discussion on filesystem support for block sizes larger than the usual 4KB
page size, 
which followed up on discussion from last year .  While the
session was meant to look at the intersection of larger block sizes
with atomic block writes  that avoid torn
(partial) writes (which was also discussed last year ), it mostly focused on 
the
filesystem side.  Over time, the
block sizes offered by storage devices have risen from the original
512bytes; Chamberlain
wanted to discuss filesystem support for block sizes larger than 4KB.
