Hi all, Attached is the v2 of the patch. I added the optimization that Sawada-san suggested for DropRelFileNodeBuffers, although I did not acquire the lock when comparing the minBlock and target block.
There's actually a comment written in the source code that we could pre-check buffer tag for forkNum and blockNum, but given that FSM and VM blocks are small compared to main fork's, the additional benefit of doing so would be small. >* We could check forkNum and blockNum as well as the rnode, but the >* incremental win from doing so seems small. I personally think it's alright not to include the suggested pre-checking. If that's the case, we can just follow the patch v1 version. Thoughts? Comments and reviews from other parts of the patch are also very much welcome. Regards, Kirk Jamison
