+Subject: [PATCH] RHEL: aarch64: fixes statsnoop and opensnoop
+
+On aarch64 the open syscall has been dropped. Only openat remains,
+wich is called by libc open() function.
+
+The state of *stat* syscalls, is a mess. They are several generations
+of the system calls, and not all arches provides all of them. For
+instance, new(l)stat are missing from aarch64.
+
+The only way I can think of fixing thess is RHEL-8 only arch specific
+patches.
