In general you shouldn't expect commits to be visible in
a git branch before they get merged -- the QEMU process
is not exactly identical to the kernel one.

For a particular patch on the mailing list, you can get a git branch
with it applied by looking for the patch in https://patchew.org/QEMU/
if that's more convenient than just applying it by hand.

We also don't tend to want patches hanging around for testing
before they get merged[*] -- we figure that "in upstream git"
is the place that actually gets tested in practice; almost
nobody will be working with or testing anything else.

[*] The fix Jason refers to here that's in MST's pullreq
unfortunately hasn't made it upstream as quickly as I
would like, due to a combination of things including us
having to pause CI for a week when we ran out of minutes.
