It is a hybrid of process_vm_readv() and vmsplice().

vmsplice can map memory from a current address space into a pipe.
process_vm_readv can read memory of another process.

A new system call can map memory of another process into a pipe.

ssize_t process_vmsplice(pid_t pid, int fd, const struct iovec *iov,
                        unsigned long nr_segs, unsigned int flags)

All arguments are identical with vmsplice except pid which specifies a
target process.

Can we have a man page for this new syscall please?

I think we can add a description for process_vmsplice into
man2/vmsplice.2. The patch is attached.

Thanks,
Andrei

Thanks,

Michael
