Hi Stefan, I am Akira Hayakawa, the upstream maintainer of the kernel module.
In dm-writeboost 2.2.6 which was released last weekend, I already fixed the issue https://github.com/akiradeveloper/dm-writeboost/commit/08b96fcad9d223aa80f9ac76ddb677e056066b48 I saw that dm-writeboost in Ubuntu is bit old and I want you to immediately update to the upstream release. Very important fixes have been included since 2.2.3, including resolving a year-long read-caching bug. Please see the ChangeLog https://github.com/akiradeveloper/dm-writeboost/blob/v2.2.6/ChangeLog As always, I hope Dmitry Smirnov is going to submit to Debian and please apply it to Ubuntu ASAP.
