11*d9bfcfdcSHuang Ying		If set to true, the VMA based swap readahead algorithm
12*d9bfcfdcSHuang Ying		will be used for swappable anonymous pages mapped in a
13*d9bfcfdcSHuang Ying		VMA, and the global swap readahead algorithm will be
14*d9bfcfdcSHuang Ying		still used for tmpfs etc. other users.  If set to
15*d9bfcfdcSHuang Ying		false, the global swap readahead algorithm will be
