Thanks Scott. There was a problem in creating this patch:
patching file testcases/kernel/syscalls/ipc/msgctl/msgctl10.c
Hunk #1 succeeded at 452 with fuzz 1.
patching file testcases/kernel/syscalls/ipc/msgctl/msgctl10.c
Hunk #1 FAILED at 452.
1 out of 1 hunk FAILED -- saving rejects to file
testcases/kernel/syscalls/ipc/msgctl/msgctl10.c.rej
However due to a trivial patch i could make the changes.
Regards--
