Subject: [PATCH 0/3] block: Improve bio_set_op_attrs() robustness
Date: Wed, 14 Sep 2016 10:42:37 +0200	[thread overview]
Message-ID: <35e3cdd6-8983-6c84-cb4c-9a7be15aea55@sandisk.com> (raw)

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.
