The procfs-guide claims that 'the parameter start doesn't seem to be used
anywhere in the kernel'. This is out of date. In linux/fs/proc/generic.c
we find a very nice description of the parameters to read_func. The
appended patch replaces the bogus description with this (as far as I know)
accurate one.
