Starting with the first two steps in stable-kernel-rules.rst: Rules on what kind of patches are accepted, and which ones are not, into the "-stable" tree: - It must be obviously correct and tested. - It cannot be bigger than 100 lines, with context. > Plus all the testing we have for the stable trees, yes.

I am not aware of any public CI being done _at all_ done on vhost-scsi, by CKI or everyone else. So autoselection should be done only on subsystems that have very high coverage in CI. Paolo
