Subjectcancel_work_sync() can cause priority invertion
Date
Hi

For those who care about linux RT behavior:

while analyzing traces, just found priority inversion caused by RT task
calling cancel_work_sync(), while work item in question is executing in
non-RT kworker that was preempted for significant time.

WBR,
Nikita Yushchenko
