Many [kdmflush] on dom0

Hi,

I just did 'top' and noticed a pretty high number of process running
at dom0. After trying to determine the cause of this I discovered that
I have:

# ps aux | grep kdmflush | wc
# 157

More than 150 [kdmflush] threads, some there since two days ago.

- From https://askubuntu.com/questions/986211/what-is-kdmflush
- ----
kdmflush is used by Device Mapper to process deferred work that it has
queued up from other contexts where doing immediately so would be
problematic.
- ----

So having threads from some days ago seems pretty dangerous.

This is probably not fault of Qubes[1], but maybe somebody has some
info about it.

Regards.
