Is there a plan when to require a higher Linux kernel version and which version will then be used as minimum? Some background on my question: On s390x, unfortunately the direct socket syscalls are not used due to the __ASSUME_* macro undefines in sysdeps/unix/sysv/linux/s390/kernel-features.h if Linux kernel version <4.3 is used.
