Debt sets the initial delay duration which is decayed over time. The current debt reduction halved the debt but didn't change the delay. It prevented future debts from increasing delay but didn't do anything to lower the existing delay, limiting the mechanism's ability to reduce unnecessary idling. Reset iocg->delay to 0 after debt reduction so that iocg_kick_waitq() recalculates new delay value based on the reduced debt amount.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
