The patch is accept and Linus expresses his anger at what he thinks is a repeating pattern of behavior (to cause regressions, break userspace and refuse to fix the cause of the breakage forcing kernel devs to work around the matter). He also decides to ban systemd maintainer from committing to the kernel hth,
