Subject: [bug] unable to handle kernel paging request when running btrfs/011
Date: Fri, 19 Feb 2016 21:41:48 +0800 [thread overview]
Message-ID: <56C71B9C.8090700@oracle.com> (raw)
Saw below warn leading to bug when running btrfs/011, not
reproducible. Any idea ?
------
static void __queue_work(..)
{
::
/* if draining, only works from the same workqueue are allowed */
if (unlikely(wq->flags & __WQ_DRAINING) &&
WARN_ON_ONCE(!is_chained_work(wq))) <---
return;
and then btrfs reported..
BUG: unable to handle kernel paging request
(gdb) list *btrfs_destroy_workqueue+0x1f
0x6a43f is in btrfs_destroy_workqueue (fs/btrfs/async-thread.c:350).
345 }
346
347 static inline void
348 __btrfs_destroy_workqueue(struct __btrfs_workqueue *wq)
349 {
350 destroy_workqueue(wq->normal_wq); <---
351 trace_btrfs_workqueue_destroy(wq);
352 kfree(wq);
353 }
354
------
Thanks, Anand
