Rename the write_version lock field to write_seq and get it from the core seq in the super block. We're doing this to create a relationship between a client transaction's seq and a lock's write_seq. New transactions will have a greater seq than all previously granted write locks and new write locks will have a greater seq than all open transactions. This will be used to resolve ambiguities in item merging as transaction seqs are written out of order and write locks span transactions. Signed-off-by: Zach Brown <zab@versity.com>
