Oh please, stop that.  Network can be done in userspace.  NFS can be
done in userspace.  Filesystems can be done in userspace.  You need a
better reason than that.

Now the pressure to add progress bar and other chrome, I can
understand.  Not wanting the chrome in the kernel, I understand even
more.  Deciding the solution for that is to more everything in
userspace and end up with the quality and stability of the suspend
fonctionality hostage to the quality of chrome code, I don't
understand that one.  Have you seen the state of multimedia playing
applications lately, where chrome won over functionality?  It's
dreadful, even if flashy.

Why don't you try to design the system so that the progress bar can't
fuck up the suspend unless they really, really want to?  Instead of
one where a forgotten open(O_CREAT) in a corner of graphics code can
randomly trash the filesystem through metadata corruption?

  OG.
