schedule_deferred() currently requires the rq lock to be held so that it can use scheduler hooks for efficiency when available. However, there are cases where deferred actions need to be scheduled from contexts that don't hold the rq lock. Split into schedule_deferred() which can be called from any context and just queues irq_work, and schedule_deferred_locked() which requires the rq lock and can optimize by using scheduler hooks when available. Update the existing call site to use the _locked variant. Reviewed-by: Emil Tsalapatis <emil@etsalapatis.com> Signed-off-by: Tejun Heo <tj@kernel.org> |

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 reStructuredText 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.
