# \[PATCH\] HID: usbkbd: Avoid GFP\_ATOMIC when GFP\_KERNEL is possible - From: Hyeonggon Yoo \ - Date: 2021-05-29 10:04:06 - List: linux-usb - Page: https://ratatoskr.run/linux-usb/2021/05/1395695 - Thread: https://ratatoskr.run/linux-usb/2021/05/1395695/t.md ```text usb_kbd_alloc_mem is called in usb_kbd_probe, which is not in atomic context. So constraints can be relaxed here. Use GFP_KERNEL instead of GFP_ATOMIC.
