Hi Sawada-san,
Thanks for the updated patch. Some comments:
1.
+ * already aborted, we discards all changes accumulated so far and ignore
+ * future changes, and return true. Otherwise return false.
we discards/we discard
2. In function ReorderBufferCheckTXNAbort(): I haven't tested this but I
wonder how prepared transactions would be considered, they are neither
committed, nor in progress.
