The problem with userland filesystems is that we may have little control
as theses may be third pary programs. Should kernel threads trust theses
processes in order to run as intended?

One way to fix that may be to have one ioflush thread for each userland
filesystem. That way a broken filesystem will not prevent ioflush from
working for others. But we have hit similar problems with others kernel
threads.
