If anyone has any objections, please let me know. ------------------ From: Asias He commit 472b72f2db7831d7dbe22ffdff4adee3bd49b05d upstream. The page++ is wrong. It makes bio_add_pc_page() pointing to a wrong page address if the 'while (len > 0 && data_len > 0) { ... }' loop is executed more than one once.
