Having issue stopping cache with latest kernel

[sjoshi10]

Description

I am having an issue where when I run casadm --stop-cache -i 1 --no-data-flush, it hangs without any output. This is only having an issue with kernel version 6.8.0-111-generic

Expected Behavior

I should be able to stop cache without any issues.

Actual Behavior

Running casadm --stop-cache -i 1 --no-data-flush hangs

Steps to Reproduce

Upgrade to kernel 6.8.0-111-generic and create cache with origin.

casadm -L
type    id   disk        status    write policy   device
cache   1    /dev/dm-0   Running   wb             -
└core   1    /dev/dm-1   Active    -              /dev/cas1-1

Run this command casadm --stop-cache -i 1 --no-data-flush

Context

I am not able to stop cache.
