The following commit broke compilation commit d5178578bcd461cc79118c7a139882350fe505aa Author: Johannes Thumshirn <jthumshirn@xxxxxxx> Date: Mon Jun 3 16:58:57 2019 +0200 btrfs: directly call into crypto framework for checksumming ERROR: "crc32c_impl" [fs/btrfs/btrfs.ko] undefined! ERROR: "crc32c" [fs/btrfs/btrfs.ko] undefined! Obviously if we call directly libcrc32c, we may not remove a dependency. Moreover, module soft dependency works only on most, but all module init tools (for example, busybox). -- With Best Regards, Andy Shevchenko
