RH-Commit: [1/11] 028e310f65eaad098ef62bdb8a5d30b9a5cd32e2
|
||
|
|
|
||
|
|
We always do the flush when finishing one round of scan, and during
|
||
|
|
complete() phase we should scan one more round making sure no dirty page
|
||
|
|
existed. In that case we shouldn't need one explicit FLUSH at the end of
|
||
|
|
complete(), as when reaching there all pages should have been flushed.
