checkpatch.pl stalls on net/decnet/dn_fib.c

[John Daiker]

Andy,

Was running checkpatch.pl on the entire tree today (because my disk 
loves to get thrashed like that...)  Found what seems to be a stall/hang 
while running checkpatch.  I know nothing of the internal workings of 
checkpatch.pl, but hope that you're able to sniff this one out!

./scripts/checkpatch.pl --file ./net/decnet/dn_fib.c  --debug values=9 
types=9 possible=9 attr=9

Hope this helps!  Let me know if I can assist in debugging at all.
