What I generally do (and what's best practice in general for cross tree
work) is apply patches on topic branches and then create a signed tag
for anything that's being merged into another tree.  That both means
we've got a signed tag for the chain of trust in the code and means that
only the specific dependency gets pulled into other trees rather than
everything that's queued.  Minimising what's pulled in makes pull
requests look cleaner and avoids noise from in development code
appearing in other trees (eg, any bugs in other code that's not quite
ready won't get merged).

In my specific trees nobody should ever merge my for-FOO branches,
they're rebuilt frequently - the topic branches are fast forward only
and intended for that (though like I say a signed tag is best).  Linus
complains about keeping the for-FOO branches fast forward
only.

Makes sense to me modulo the signed tag thing above.
