//! The linux_raw backend.
//!
//! This makes Linux syscalls directly, without going through libc.
//!
//! # Safety
//!
//! These files performs raw system calls, and sometimes passes them
//! uninitialized memory buffers. The signatures in this file are currently
//! manually maintained and must correspond with the signatures of the actual
//! Linux syscalls.
//!
//! Some of this could be auto-generated from the Linux header file
//! <linux/syscalls.h>, but we often need more information than it provides,
//! such as which pointers are array slices, out parameters, or in-out
//! parameters, which integers are owned or borrowed file descriptors, etc.
