The API (kernel syscall) as defined does not support LFS.
I wonder does it really need to? I mean, a loop calling sendfile for
2GB (or whatever) at a time is almost as good, if not better in some
ways.
The "extent based" filesystems offer flatter performance, and
while I can't determine if ReiserFS is exactly of that type, it
too offers fast and flat performance.
Reiserfs (v3) isn't extent based but does perform pretty well. When I
was messing large numbers of with (what at the time were) large files
of 50GB or so, XFS proved to be very effective.
