Change Details

Move all compatibility code for Linux timerfd into the FreeBSD base kernel. The timerfd interface is traditionally a set of syscalls, but this implementation creates pseudo syscalls using specialfd and ioctl()s. File descriptor creation in timerfd_create() is exposed through the specialfd interface. The timerfd_gettime() and timerfd_settime() functions are exposed through `ioctl()` calls. All of these functions are accessible in userspace through a set of libc wrappers.

The timerfd interface is traditionally composed of non-standard Linux system calls that operate on interval timers. Overhaul all compatibility code for Linux timerfd and integrate it into the FreeBSD base kernel. Unlike per-process timers, timerfd timers are identified by special file descriptors and may be passed to other processes.
