If anyone has any objections, please let me know. ------------------ From: Chengguang Xu [ Upstream commit c36ed50de2ad1649ce0369a4a6fc2cc11b20dfb7 ] On currently logic: when I specify rasize=0~1 then it will be 4096. when I specify rasize=2~4097 then it will be 8192. Make it the same as rsize & wsize.
