We've seen series with fifty-something patches on this list before.
My (generic) advice:

 1. Send in installments, early and often.  It would not be fun if the
    first ten patches have a fatal flaw that means the later ones have
    to be reworked.

 2. Make sure the cover letter makes people want to read the later
    patches.  Make sure each patch has a commit message that motivates
    it alone or explains how it fits into the larger picture.

 3. When a patch is not intended to cause any functional change, say
    so, so reviewers can check that.

 4. Include test scripts declaring what effect (or lack thereof) each
    patch is supposed to have.

 5. "Smallest irreducible step" is not necessarily the appropriate
    granularity when publishing.  "Largest piece that a person would
    want to review, apply, or revert independently" is.
