Missing include in src/rocksdb/db/builder.cc

[Willem Jan Withagen <wjw@digiware.nl>]

I'm running into:

In file included from db/builder.cc:16:
In file included from ./db/compaction_iterator.h:14:
In file included from ./db/compaction.h:13:
./util/mutable_cf_options.h:28:21: error: no member named 
'soft_pending_compaction_bytes_limit' in 'rocksdb::Options'; did you mean
       'hard_pending_compaction_bytes_limit'?
             options.soft_pending_compaction_bytes_limit),
                     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                     hard_pending_compaction_bytes_limit
/usr/local/include/rocksdb/options.h:517:12: note: 
'hard_pending_compaction_bytes_limit' declared here
   uint64_t hard_pending_compaction_bytes_limit;
            ^
Due to a missing:
	#include "util/options_helper.h"

Does anybody have experience with upstreaming this to Rocksdb for the 
version Ceph is using.
I seem to remember somebody posting about this...

Thanx,
