From 2228768885e0b92c0f7b276cc61b8974e7aed724 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Fri, 3 May 2013 11:16:18 -0400 Subject: [PATCH] ring-buffer: Select IRQ_WORK As the wake up logic for waiters on the buffer has been moved from the tracing code to the ring buffer, it requires also adding IRQ_WORK as the wake up code is performed via irq_work. This fixes compile breakage when a user of the ring buffer is selected but tracing and irq_work are not.
