In commit 6e890c5d5021 ("vhost: use vhost_tasks for worker threads"),
vhost removed the support for the kthread API. However, there are
still situations where there is a request to use kthread.
In this RFC, the support of kthread is added back. Additionally,
a module_param is added to identify which mode we are using, and
a new UAPI is introduced to allow the userspace app to set the
mode they want to use.Cindy Lu (7): vhost: Add a new module_param for enable kthread vhost: Add kthread support in function vhost_worker_queue() vhost: Add kthread support in function vhost_workers_free() vhost: Add the vhost_worker to support kthread vhost: Add the cgroup related function vhost: Add kthread support in function vhost_worker_create vhost: Add new UAPI to support changing Kthread mode drivers/vhost/vhost.c | 241 +++++++++++++++++++++++++++++++++++-- drivers/vhost/vhost.h | 1 + include/uapi/linux/vhost.h | 2 + 3 files changed, 235 insertions(+), 9 deletions(-) -- 2.45.0
