     5  // This file implements accept for platforms that provide a fast path for
     6  // setting SetNonblock and CloseOnExec, but don't necessarily have accept4.
     7  // This is the code we used for accept in Go 1.17 and earlier.
     8  // On Linux the accept4 system call was introduced in 2.6.28 kernel,
     9  // and our minimum requirement is 2.6.32, so we simplified the function.
    10  // Unfortunately, on ARM accept4 wasn't added until 2.6.36, so for ARM
    11  // only we continue using the older code.
