timerfd: Move implementation from linux compat to sys/kern 2023-08-24T20:28:56+00:00 Jake Freeland jfree@freebsd.org 2023-08-24T04:39:54+00:00 af93fea710385b2b11f0cabd377e7ed6f3d97c34 Move the timerfd impelemntation from linux compat code to sys/kern. Use it to implement the new system calls for timerfd. Add a hook to kern_tc to allow timerfd to know when the system time has stepped. Add kqueue support to timerfd.
