2.1.0

How you caught the bug is interesting enough to be mentioned in the commit message, but the nature of the bug surely is more interesting than that. Suggest to change the subject to

qtest/ahci: Fix a bit mask expression

Perhaps it can be fixed up on commit.

If it goes in through trivial,

can we change this to Markus's suggestion?

Thank you,

Applied to trivial, changing subject to the one suggested by Markus.

Thanks,
