2) explain better in the quick help below what "exact" means.
Also is it possible to test just patches without repository?
Can you add this feature when you simply submit a message ID
to it and it uses lore.kernel.org for the patch or series?

Yeah, I've just thought about it too when I was correcting the command.

Thanks, these are good suggestions!
The first one is easy to do (we actually already support that
internally, so only a small change is needed), the second one is a bit
trickier, but I'll look into that.

JFYI:
20230828145824.3895288-1-andriy.shevchenko@linux.intel.com
Can be used for testing.
So I like to write
#syz test patch: 20230828145824.3895288-1-andriy.shevchenko@linux.intel.com
The responses can be (among others?):
1/ tested and test results;
2/ not found.

"patch:" does not look like a valid git repo address.

FTR I've just sent two PRs:
1) Support `#syz test` without arguments -- in that case, syzbot
checks out the latest commit on the fuzzed branch.
2) Parse all kinds of email titles in `#syz dup`.
I'll deploy them soon.

Thanks for the idea!
I've filed https://github.com/google/syzkaller/issues/4182
The biggest problem is to figure out the command syntax that'd also
let us specify the tree on which to apply the patch. Or to restrict
the patch testing to either apply the patch from lore on top of the
fuzzed tree or to accept repo/branch/patch explicitly.

Ah, that's easy to solve. I've commented there.
