Why I cannot see the flush process in my system?
February 12, 2017 12:59PM
Hi All,

I am learning the writeback mechanism in kernel.
I have two machines. Both are running Fedora.
One is the real machine. The other one is VM.
In the real machine, I can see there are three kdmflush process. However, in the VM, I can see nothing about the flush process.
What's happened there?

PS: I try different kernel version: 4.6.7, 4.4.8, 4.9. The same thing happens.
