Subject: [PATCH -next] hwlat: depends on RING_BUFFER (build fix)
Date: Mon, 22 Jun 2009 08:51:53 -0700 [thread overview]
Message-ID: <4A3FA899.3040402@oracle.com> (raw)
In-Reply-To: <20090622181920.496d160e.sfr@canb.auug.org.au>
From: Randy Dunlap <randy.dunlap@oracle.com>
hwlat_detector build fails because it uses ring_buffer interfaces
without depending on RING_BUFFER.
hwlat_detector.c:(.text+0x8d906): undefined reference to `ring_buffer_reset'
hwlat_detector.c:(.text+0x8d98c): undefined reference to `ring_buffer_free'
hwlat_detector.c:(.text+0x8dd16): undefined reference to `__ring_buffer_alloc'
hwlat_detector.c:(.text+0x8df15): undefined reference to `ring_buffer_free'
hwlat_detector.c:(.text+0x8e100): undefined reference to `ring_buffer_write'
hwlat_detector.c:(.text+0x8e239): undefined reference to `ring_buffer_consume'
hwlat_detector.c:(.text+0x8e2ac): undefined reference to `ring_buffer_event_data'
