I've been sitting on this patch because afaik the problem which it purports
to fix remains unfixed.

Should I drop it??

Thanks.



From: "Jari Takkala" <[EMAIL PROTECTED]>

Fix a problem where output from /proc/net/arp skips a record when the full
output does not fit into the users read() buffer.

To reproduce: publish a large number of ARP entries (more than 10 required
on my system).  Run 'dd if=/proc/net/arp of=arp-1024.out bs=1024'.  View
the output, one entry will be missing.
