according to the device drivers guide 'Linux on Z and LinuxONE - Device Drivers, Features, and Commands - Development stream (Kernel 4.18)' (page 482) http://public.dhe.ibm.com/software/dw/linux390/docu/l418dd35.pdf there is no limitation mentioned and it should just work - even with GBs of cachesize. Hence looping in IBM and reverse mirroring this bug.
