- Initialize 'ret' local variables on fprobe_handler() to fix the smatch warning. With this, fprobe function exit handler is not working randomly. - Fix to use preempt_enable/disable_notrace for rethook handler to prevent recursive call of fprobe exit handler (which is based on rethook) - Fix recursive call issue on fprobe_kprobe_handler(). - Fix to detect recursive call on fprobe_exit_handler(). - Fix to make all arch-dependent rethook code notrace. (the arch-independent code is already notrace) -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmRmKgQACgkQ2/sHvwUr PxvlCgf+OJk5O9IJlTgqDV6JNPsTzFS7qqyAyQmZW9Bj8STfWAIRxa0zeGbZE58K 5LwgzAj+SqzYRwIvzzZ3xsA5j7f1Wj7wG0TQgmpnIW+hprwDrLsUhoZ5s1D/Ojel A4rAnqCrgnh5m5SenU2QCUngGKn004j4RASaZvRELDyvyIkBSqNhswCH8ZWGPror KuCu5AmEnFagYl0lmNL3H2aCITAg3QEK+fE6iR+lYsqfR3xbs4YAcqiylHBdY0wX ssK7LVdRmv7O6TxSj4P2ohDvLJP3eL9bVirsJpg0OVbqWJCs65T2rJJjXiKojYXf vSVWFJFK5oV98ZHfXTG9R7x0DEwc+g== =jO68 -----END PGP SIGNATURE----- Merge tag 'probes-fixes-v6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull probes fixes from Masami Hiramatsu: - Initialize 'ret' local variables on fprobe_handler() to fix the smatch warning.
