[PATCH 0/3] block: Improve bio_set_op_attrs() robustness

Hi Jens,

bio_set_op_attrs() does not yet check whether the "op_flags" field overflows into the "op" field. Since adding support for SMR requires to introduce more REQ_* flags I think it is important to have such a check. Hence this patch series. Please consider these patches for inclusion in the upstream Linux kernel.

Thanks,

Bart.
