From 06e86bde8886aca3e1cd8cbc948cff7a103f97ab Mon Sep 17 00:00:00 2001 From: "Joe Richey joerichey@google.com" Date: Mon, 17 Apr 2017 12:45:30 -0700 Subject: vendor: adding in golang.org/x/sys/unix package This commit adds in the golang.org/x/sys/unix package. This package provides a low-level interface to unix syscalls. We will uses this package instead of the built-in "syscall" package because the syscall package is locked down (https://golang.org/pkg/syscall) and is not exposing any new kernel functionality. In fact, this is actually a patched version of the x/sys/unix package pending review (first part: https://go-review.googlesource.com/c/37943). The version included in this commit exposes all of the filesystem encryption kernel interfaces to Go code.
