    Re: data loss when using kernel 4.19

    short answer is yes. long answer is that it needs a very specific set of circumstances to manifest so don't panic

    The reason why this wasn’t caught in testing, and why it only affected a relatively small number of people, is that it required the following conditions to be met:
    1. The drive must not have an IO scheduler configured
    2. The driver must regularly have a resource starvation condition
    3. The driver must maintain state in the request over multiple ->queue_rq() invocations

    AFAIK blk-mq is not enabled by default on Fedora kernels, so short answer is no.
