Subject: Re: [PATCH v3 07/10] block: introduce BIP_CHECK_GUARD/REFTAG/APPTAG bip_flags

Message-ID: <20240824083553.GF8805@lst.de> (raw)

This patch came in twice, once with a "block" and once with a
"block,nvme" prefix. One should be fine, and I think just block is
the right one.
How do we communicate what flags can be combined to the upper layer
and userspace given the SCSI limitations here?

Maybe describe the flags here like the other ones?
