Bug Description
/** Request IO burst and wake page_cleaner up.
@param[in] lsn_limit upper limit of LSN to be flushed */
void
buf_flush_
lsn_t lsn_limit)
{
/* adjust based on lsn_avg_rate not to get old */
lsn_t lsn_target = lsn_limit + lsn_avg_rate * 3;
with lsn_limit == LSN_MAX, lsn_target will be some much smaller than required value.
This is a regression of the parallel doublewrite patch.
