I don't think it's a good idea to boost the default fsblock size beyond 4k until we get further into the era where the major distros are shipping 6.12 kernels. I wouldn't want to deal with people accidentally ending up with an 8k fsblock filesystem that they can't mount on fairly new things like RHEL9/Debian12/etc. --D > Thoughts? > > Luis >
