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.
