Kthread worker is a single thread workqueue which can be used in cases where specific kthread association is necessary, for example, when it should have RT priority or be assigned to certain cgroup. This change implements Linux v4.9 interface which mostly hides kthread internals from users thus allowing to use ordinary taskqueue(9) KPI. As kthread worker prohibits enqueueing of already pending or canceling tasks some minimal changes to taskqueue(9) were done. taskqueue_enqueue_flags() was added to taskqueue KPI which accepts extra flags parameter. It contains one or more of the following flags: TASKQUEUE_FAIL_IF_PENDING - taskqueue_enqueue_flags() fails if the task is already scheduled to execution. EEXIST is returned and the ta_pending counter value remains unchanged. TASKQUEUE_FAIL_IF_CANCELING - taskqueue_enqueue_flags() fails if the task is in the canceling state and ECANCELED is returned.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
