+This is a rewrite of the commit for the pre-64-bit time_t version of
+the msgctl handling. Similar to semctl we want the RHEL8 handling of
+the unknown commands to be the same as upstream.

+    sysvipc: Return EINVAL for invalid msgctl commands
+    
+    It avoids regressions on possible future commands that might require
+    additional libc support.  The downside is new commands added by newer
+    kernels will need further glibc support.
+    
+    Checked on x86_64-linux-gnu and i686-linux-gnu (Linux v4.15 and v5.4).
