to be able to read and write large buffers below /proc.
The buffers and file offsets are handled dynamically
on the required buffer size at read, that is lseek(2)
is used to determine this size. Large buffers at
write are split at a delimeter into pieces and also
lseek(2) is used to write each of them.

/proc/sys, not using the seq_file API at the kernel side,
will return EOF on a second read.

system control names of the kernel parameters should be shown.
Avoid leaking tmpname in case of a pattern mismatch.
