Moreover, patches 6,7 add support for zero-copy of iscsi ImmediateData for small IOs (up to 8K where all the command data comes inline). Supporting zero-copy of ImmediateData for all IO sizes would require modification of the data buffer allocation logic (which might not worth the trouble). Given that larger IOs are less latency critical, we settle without it for now.

Also, a v3.10+ stable tag has been added for patch #1, #2 and #5 as well. As patch #5 depends on the earlier commit ce9a9fc20a, it will need to be included in stable first for this to apply cleanly.
