+Subject: bpf, x86: initialize the variable "first_off" in save_args()
+
+From: Menglong Dong <imagedong@tencent.com>
+
+commit 492e797fdab25f2d8eb1b6bb3236f4aac474f878 upstream.
+
+As Dan Carpenter reported, the variable "first_off" which is passed to
+clean_stack_garbage() in save_args() can be uninitialized, which can
+cause runtime warnings with KMEMsan. Therefore, init it with 0.
+
+Fixes: 473e3150e30a ("bpf, x86: allow function arguments up to 12 for TRACING")
