![]() pcistub_reg_add() is never called in atomic context. pcistub_reg_add() is only called by pcistub_quirk_add, which is only set in DRIVER_ATTR(). Despite never getting called from atomic context, pcistub_reg_add() calls kzalloc() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it.
