Linux kernel source tree
e61e6c415b
The overflow_work is using system wq to do overflow checks and updates for PHC device timecounter, which might be overhelmed by other tasks. But there is dedicated kthread in PTP subsystem designed for such things. This patch changes the work queue to proper align with PTP subsystem and to avoid overloading system work queue. The adjfine() function acts the same way as overflow check worker, we can postpone ptp aux worker till the next overflow period after adjfine() was called.

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.
