Message-ID: <CALMA0xYT9H7fZx2gnjf_8DrXpLPVHkuKtYbkm0MbqsSZTLf=NA@mail.gmail.com> Date: Sat, 11 May 2024 18:47:50 +0800 From: Zhixu Liu <zhixu.liu@...il.com> To: rcu@...r.kernel.org Cc: linux-input@...r.kernel.org, linux-kernel@...r.kernel.org Subject: Re: kernel panic when build w/ CONFIG_HID_BPF=y Hi, As described in the last email, I thought the kernel panic was related to CONFIG_HID_BPF, but it seems not for today's panic. Following panic log is found on a macmini7.1 w/ CONFIG_HID_BPF disabled, the panic log is highly similar w/ the log with CONFIG_HID_BPF enabled. It seems related to RCU?
