[PATCH v7 06/11] arm64/ptrace: Expand secure_computing() in place
From: Jinjie Ruan <hidden>
Date: 2025-11-17 13:31:22
Also in:
linux-kselftest, lkml
Subsystem:
arm64 port (aarch64 architecture), ptrace support, the rest · Maintainers:
Catalin Marinas, Will Deacon, Oleg Nesterov, Linus Torvalds
The generic entry expand secure_computing() in place and call __secure_computing() directly. In order to switch to the generic entry for arm64, refactor secure_computing() for syscall_trace_enter(). No functional changes. Signed-off-by: Jinjie Ruan <redacted> --- arch/arm64/kernel/ptrace.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)
