How can I write a programm on host to ptrace processes on uml in SKAS mode  ?
Is there is some examples about ptrace(PTRACE_SWITCH_MM,
userspace_pid, 0, mm_fd)?
Eager to hear from you .
Many thanks.

skas3 or skas0?  Sounds like you're interested in skas3.

But why does it have to be done from the host rather than from inside UML?

In UML, sure.  But it looks like you found that.
