I ran into this build error on linux-next: drivers/infiniband/hw/hns/hns_roce_eq.c:477:8: error: unknown type name 'irqreturn_t' static irqreturn_t hns_roce_msi_x_interrupt(int irq, void *eq_ptr) ^~~~~~~~~~~ drivers/infiniband/hw/hns/hns_roce_eq.c: In function 'hns_roce_msi_x_interrupt': drivers/infiniband/hw/hns/hns_roce_eq.c:485:9: error: implicit declaration of function 'IRQ_RETVAL'; did you mean 'BPF_RVAL'? [-Werror=implicit-function-declaration] return IRQ_RETVAL(int_work); I have bisected this to a seemingly unrelated change that happened to remove some indirect header inclusions. Simply including the required header explicitly fixes the build failure.
