Just as an FYI, if you *really* hate having to
review the reformatting and modern coding
standards changes, I can produce a more
minimal patch that merely modifies the
existing ugly code to achieve the same
effect (calling read_file() instead of
SMB_VFS_LSEEK/SMB_VFS_READ) - but that
would leave a ton of really ugly code
alone (with massive functions and
indentation left as-is).

So currently I prefer my reformatting,
but I'm flexible on this :-).
