Hi!
Maybe _bt_readpage(scan, dir, start, true) needed at this line:
?
Do we really need to try prechecking the continuescan flag here?
And the current "false" in the last arg does not match the previous code before 06b10f80ba
and the current comment above.
Would be very grateful for clarification.
With the best regards!
