Since 'iov_iter_extract_pages()' may allocate new array of pages even when it returns non-zero error value, matching cleanup with 'vfree()' should be performed on all return paths afterwards. So adjust 'bio_integrity_map_user()' to ensure that both 'pages' and 'bvec' arrays are always freed on return. Fixes: 8582792 ("block: bio-integrity: Fix null-ptr-deref in bio_integrity_map_user()") Fixes: 492c5d4 ("block: bio-integrity: directly map user buffers") Signed-off-by: Dmitry Antipov <dmantipov@yandex.ru>
