| Which one do you want? The boolean result as the value to be returned or
| the index if it is < 0?
| 
It is the first value. The test is only there to avoid accessing the
array with an invalid index, which would happen if an unknown `feat_num'
is passed - as for unknown features there is no default value.

| I tried to check on the other 4 patches on this series to check if usage
| clarified if it was correct, but there is no use of
| dccp_feat_default_value() on this 5 patches, perhaps it could be
| deferred to when it actually gets used?
| 
Yes thanks, while I have ensured that all patches are bisectable, a few
functions may be declared where the logical fit was better. I will place
it where it is first used, in the patch entitled "dccp: Registration
routines for changing feature values"

I am waiting before resubmitting - please take a look at patches 3-5 as well.
