"Swap in" an entire process?

"Swap in" an entire process?

[Konstantin Kudin]

 I have a question. Is there some way under linux to
"swap in" an entire process that got partially swapped
out?

 Basically, I want all the pages for a given PID
returned to RAM if they were paged out.

 And vice versa, is there a way to "swap out" a
process by some command?

 Thanks!

 Konstantin

The process to swap in can do that with mlockall().

No, but munlockall will allow it to be swapped
again. It will swap out while sleeping gradually, since it dirties no
pages at all.

But there is no external trigger mechanism for this in Linux right now.
