Should this be considered a rule until further LFS improvements are made
or is this unlikely to change?
I'm starting to wonder, with all the LFS tweaking required for
performance and then the underlying issues with regards to the above and
trigerable panics using lfs -> smb/cifs, is it worth using LFS at all?
I'm not sure if I'm seeing the benefits.
