Hi folks, After a long time effort, now bcache can work on s390 machine. The kernel part is ready since Linux v5.4, the bcache-tools should be updated too from, https://git.kernel.org/pub/scm/linux/kernel/git/colyli/bcache-tools.git/ The update for bcache-tools-1.1 is necessary, it fixes a super block checksum issue which makes kernel code treats the registering device as broken. I only test bcache on a machine with vendir_id: IBM/S390, not sure whether it also works on s390x. If you have interest to deploy bcache on s390 or other big endian machines, I will appreciate if you may offer a result whether bcache works or not on your machine. Of cause if it does not work, I'd like to look into the problem and try to fix them. BTW. Since bcache-tools is not updated for quite a long time, now I start to take the maintenance of bcache-tools. And please permit me to thank Shaoxiong Li for contributing many useful patches. Just for your information. -- Coly Li
