An iocg may have 0 debt but non-zero delay. The current debt forgiveness logic doesn't act on such iocgs. This can lead to unexpected behaviors - an iocg with a little bit of debt will have its delay canceled through debt forgiveness but one w/o any debt but active delay will have to wait out until its delay decays out. This patch updates the debt handling logic so that it treats delays the same as debts. If either debt or delay is active, debt forgiveness logic kicks in and acts on both the same way. Also, avoid turning the debt and delay directly to zero as that can confuse state transitions. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
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.
