A constraint on the nodes requires setting wbc.nodes. I could not find a writeback_control setup that uses either of those flags and also sets wbc.nodes. And WB_SYNC_ALL is already used with another constraints on a mapping to only partially sync. If a caller in the future sets wbc.nodes plus either of those options then it is an attempt to perform these operations only on a subset of nodes. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
