Fixes for this are already in my net-2.6 tree, will send them
off to Linus later today, I was waiting for some netfilter
fixes which I just received:
commit 1386be55e32a3c5d8ef4a2b243c530a7b664c02c

dccp: fix auto-loading of dccp(_probe)
This fixes commit (38ff3e6bb987ec583268da8eb22628293095d43b) ("dccp_probe:
Fix module load dependencies between dccp and dccp_probe", from 15 Jan).
It fixes the construction of the first argument of try_then_request_module(),
where only valid return codes from the first argument should be returned.
What we do now is assign the result of register_jprobe() to ret, without
the side effect of the comparison.

commit 8ed030dd0aa400d18c63861c2c6deb7c38f4edde

dccp: fix bug in cache allocation
This fixes a bug introduced in commit de4ef86cfce60d2250111f34f8a084e769f23b16
("dccp: fix dccp rmmod when kernel configured to use slub", 17 Jan): the
vsnprintf used sizeof(slab_name_fmt), which became truncated to 4 bytes, since
slab_name_fmt is now a 4-byte pointer and no longer a 32-character array.
This lead to error messages such as
FATAL: Error inserting dccp: No buffer space available
>> kernel: [ 1456.341501] kmem_cache_create: duplicate cache cci
generated due to the truncation after the 3rd character.
Fixed for the moment by introducing a symbolic constant. Tested to fix the bug.
