btrfs: transaction: describe transaction states and transitions
Add an overview of the basic btrfs transaction transitions, including
the following states:
- No transaction states
- Transaction N [[TRANS_STATE_RUNNING]]
- Transaction N [[TRANS_STATE_COMMIT_START]]
- Transaction N [[TRANS_STATE_COMMIT_DOING]]
- Transaction N [[TRANS_STATE_UNBLOCKED]]
- Transaction N [[TRANS_STATE_COMPLETED]]
For each state, the comment will include:
- Basic explaination about current state
- How to go next stage
- What will happen if we call various start_transaction() functions
- Relationship to transaction N+1
This doesn't provide tech details, but serves as a cheat sheet for
reader to get into the code a little easier.
