Syscall

The code from Package syscall is used for wrapping syscall functions from different platforms that the standard syscall library does not provide.

Steps to produce files in the directory:

1. Clone the repo golang/sys and put your types and const definitions in the linux/types.go.
2. Run GOOS=linux GOARCH=amd64 ./mkall.sh from golang/sys/internal-branch.go1.17-vendor. Don't worry about GOARCH, it will generate the required files for all possible Linux architectures.
3. Copy the generated code ztypes_linux.go and hand-writing code types.go to this directory.
4. Add your syscall functions in syscall_unix.go.
