Is there a client in mind for this new code?  And how does it differ to
what you can already achieve by the combination of
bdrv_clear_dirty_bitmap/bdrv_merge_dirty_bitmap?

Typical S-o-b and git authorship uses a preferred legal name rather than
a single-word username (there have been exceptions made in the past, but
we try not to introduce more without good reason).  You can also teach
git to spell your name in both native UTF-8 characters and a Latinized
form, if you prefer.
