The patch titled
x86_64: Don't do syscall exit tracing twice
has been removed from the -mm tree. Its filename is
x86_64-dont-do-syscall-exit-tracing-twice.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
------------------------------------------------------
Subject: x86_64: Don't do syscall exit tracing twice
From: "Andi Kleen" <ak@xxxxxxx>
int_ret_from_syscall already does syscall exit tracing, so no need to do it
again in the caller.
This caused problems for UML and some other special programs doing syscall
interception.
Signed-off-by: Andi Kleen <ak@xxxxxxx>
