Please note that when eio is locked IO can be issued directly in both source and cache devices.

I just compiled and installed master version in kernel 4.14.158. I still face the same bug in this kernel.
Here is the stack trace:

from enhanceio.
Master version flushes cache without any problem in kernel 3.10.0. But it takes too long to fill the cache (compared to kernel 4.14) with the same sequential write workload.
from enhanceio.
I tested the master version on kernel 5.4.2 and the flush process works correctly.
