> Ritesh, can you give the following a spin - it renames sem_init as um_sem_init for UML only?

FWIW, this fixes the issue in my reproducer, so should work here too:

diff --git a/ipc/util.h b/ipc/util.h
index 5766c61aed0e..cfed40ba983c 100644
--- a/ipc/util.h
+++ b/ipc/util.h
@@ -14,6 +14,7 @@
 #include <linux/unistd.h>
 #include <linux/err.h>

 /*
  * The IPC ID contains 2 separate numbers - index and sequence number.
