The actual change here isn't bothering me, but I'm having trouble
understanding why it's needed. It doesn't appear to be a strict
functional prerequisite for 2/2.
A little more context in the commit message would be helpful.
Sample commit description:
The lease-handling code paths always know they're disposing of leases,
yet locks_dispose_list() checks flags at runtime to determine whether
to call locks_free_lease() or locks_free_lock().
Split out a dedicated lease_dispose_list() helper for lease code paths.
This makes the type handling explicit and prepares for the upcoming
lease_manager enhancements where lease-specific operations are being
consolidated.
But that reflects only my naive understanding of the patch. You
might have something else in mind.

The commit message should say *why* the change is being made and this one just left us guessing. But I *do* like the change and would rather it were kept in the series, but with a simple addition to the commit message saying that is a simplification that isn't strictly necessary. Thanks, NeilBrown

It's not. We can table this patch for now if that's preferable, but I
do think it's a worthwhile cleanup.

Nope, no ulterior motive here. It's just a nice to have cleanup that
helps to further separate the lock and lease handling code.
