    Umm. No. The object of LFS stuff is so that programs that can't
    handle large files don't shoot themselves in the foot. You don't
    need to pass O_LARGEFILE over the protocol and knfsd doesn't need
    to handle it. But with out specifying O_LARGEFILE you should
    be limited to 2GB on 32bit systems.

    Moving some of the LFS checks into the VFS does sound good.

    When I looked at one of the BSD's a while ago, they had
    a max file size in (the superblock?) and the VFS did basic
    max file size checking. And I think it handled all of the LFS
    API at the VFS layer as well. Alan these are two seperate
    but related issues.

    Putting the LFS checks, & max filesize checks into the VFS sounds
    right for 2.4.x because it fixes lots of filesystems, with just a
    couple of lines of code.
