The patch below adds a wrapper that copies the (supposedly short) name to

Is that enough? What about buffers and all that?
As m68k doesn't support highmem, all memory buffers should point to
"normal" kernel virtual memory. If any of these were a problem, we should
have noticed already.
I had a quick look at our nf* drivers, and (unless I missed something) none
of them seem to pass pointers to static data to NF calls, except for the
ID names and the buffer in arch/m68k/emu/natfeat.c:nfprint().
The latter is OK (albeit not thread-safe, but no one calls nfprint()?),
as natfeat.c is never a module.
Sorry, won’t be testing these patches for a while,
I need to concentrate on the Debian sid kernel for now.
OK. Enjoy sid, thanks!
