// Import "unsafe" because we use go:linkname.

// When using cgo, call the C library for mmap, so that we call into
// any sanitizer interceptors. This supports using the memory
// sanitizer with Go programs. The memory sanitizer only applies to
// C/C++ code; this permits that code to see the Go code as normal
// program addresses that have been initialized.

// To support interceptors that look for both mmap and munmap,
// also call the C library for munmap.
