[Drbd-dev] [PATCH 06/24] drbd: resync: fix too large bursts for very slow rates

[Philipp Reisner]

From: Lars Ellenberg <lars.ellenberg at linbit.com>

While merging adjacent dirty blocks into resync requests,
the resync rate throttle was disregarded.
For very low resync rates, the effective rate may have exceeded
the intended rate by a larger margin.
