| |
Hello RCU folks,
I like to use minimal configuration for kernel development. when building with tinyconfig + CONFIG_PREEMPT=y on arm64:
ld: kernel/rcu/update.o: in function `call_rcu_tasks': update.c:(.text+0xb2c): undefined reference to `irq_work_queue' update.c:(.text+0xb2c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `irq_work_queue' make: *** [Makefile:1155: vmlinux] Error 1
It seems RCU calls irq_work_queue() without checking if CONFIG_IRQ_WORK is enabled.
-- Thank you, You are awesome! Hyeonggon :-)
