| From | Arnd Bergmann <> | Subject | [PATCH, RFC 14/22] oprofile: always enable IRQ_WORK | Date | Thu, 2 May 2013 17:16:18 +0200 |
| |
oprofile fails to build if CONFIG_IRQ_WORK is not already enabled, because of the dependency on the RING_BUFFER code that now uses the irq work library.
kernel/built-in.o: In function `ring_buffer_unlock_commit': :(.text+0x5b8f0): undefined reference to `irq_work_queue' kernel/built-in.o: In function `ring_buffer_write': :(.text+0x5bd10): undefined reference to `irq_work_queue'
