But threading aside, I think all the posted patches are what he intended. Looks like the "3 patch series" mentioned above map to: [PATCH v2 00/26] Prep work for immutable bio vecs [PATCH v4 00/24] Prep work for immutable bio vecs [PATCH v4 1/2] block: Fix a buffer overrun in bio_integrity_split() So you can key off of "v2 xx/26" vs "v4 xx/24" vs "v4 x/2" But, yeah, not ideal..
