this is a myth; linux is free to move the page about in physical memory even if it's mlock()ed!!
Then Linux has a very odd definition of the word "locked".
And even then, the user can munlock the memory from another thread etc etc. Not a good idea.
Well, that's okay, because then the app is doing something stupid, so we don't worry about that.
get_user_pages() is used from AIO and other parts of the kernel for similar purposes and in fact is designed for it, so it better work. If it has bugs those should be fixed, not worked around!
I've been complaining about get_user_pages() not working for a long time now, but I can only demonstrate the problem with our hardware. See my other post in this thread for details.
