Almost. Just not call it a "following patch" because once this is
applied, the following one might be a different one depending on the
ordering a git command has requested. So a "later patch" would be
probably better.

Yes but you need to tell the stable people somehow that this one is a
prerequisite and that they should pick it up too.

Unless you can reorg your code this way that you don't need patch 1...
