+//! 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.
