Re: kernel panic when build w/ CONFIG_HID_BPF=y
From: Zhixu Liu
Date: Sat May 11 2024 - 06:48:39 EST
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?
