commit 27e714c007e4ad01837bf0fac5c11913a38d7695 upstream. In27cfa25895"ext2: fix fs corruption when trying to remove a non-empty directory with IO error" a funny thing has happened: - page = ext2_get_page(inode, i, dir_has_error, &page_addr); + page = ext2_get_page(inode, i, 0, &page_addr); - if (IS_ERR(page)) { - dir_has_error = 1; - continue; - } + if (IS_ERR(page)) + goto not_empty; And at not_empty: we hit ext2_put_page(page, page_addr), which does put_page(page). Which, unless I'm very mistaken, should oops immediately when given ERR_PTR(-E...) as page. OK, shit happens, insufficiently tested patches included. But when commit in question describes the fault-injection test that exercised that particular failure exit... Ow.
