| Subject: target/pscsi: Fix page increment |
| |
| From: Asias He <asias@redhat.com> |
| |
| 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. |
