Then if there is a separate pool for each cleancache pool, when a filesystem is umount'ed, it isn't necessary to walk through and delete all pages one-by-one, which could take quite awhile. ramster needs one pool for each client (i.e. machine in the cluster) for frontswap pages for the same reason, and later, for cleancache pages, one per mounted filesystem per client -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
