From a9441aea2780da8c93da1c73da860219f98438de Mon Sep 17 00:00:00 2001 From: Ayush Ranjan Date: Wed, 3 Mar 2021 10:23:55 -0800 Subject: [op] Replace syscall package usage with golang.org/x/sys/unix in pkg/. The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in the following places: - pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities are not yet available in golang.org/x/sys. - syscall.Stat_t is still used in some places because os.FileInfo.Sys() still returns it and not unix.Stat_t.
