From 7259f0d05d595b73ef312a082e628627c6414969 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Sun, 29 Oct 2006 22:46:36 -0800 Subject: [PATCH] lockdep: annotate DECLARE_WAIT_QUEUE_HEAD kernel: INFO: trying to register non-static key. kernel: the code is fine but needs lockdep annotation. kernel: turning off the locking correctness validator. kernel: [] show_trace_log_lvl+0x58/0x16a kernel: [] show_trace+0xd/0x10 kernel: [] dump_stack+0x19/0x1b kernel: [] __lock_acquire+0xf0/0x90d kernel: [] lock_acquire+0x4b/0x6b kernel: [] _spin_lock_irqsave+0x22/0x32 kernel: [] prepare_to_wait+0x17/0x4b kernel: [] lpfc_do_work+0xdd/0xcc2 [lpfc] kernel: [] kthread+0xc3/0xf2 kernel: [] kernel_thread_helper+0x5/0xb Another case of non-static lockdep keys; duplicate the paradigm set by DECLARE_COMPLETION_ONSTACK and introduce DECLARE_WAIT_QUEUE_HEAD_ONSTACK.
