Subject: ib_destroy_cm_id() versus cm callback race ?
Date: Fri, 27 Apr 2012 15:57:38 +0000	[thread overview]
Message-ID: <4F9AC1F2.5070007@acm.org> (raw)

Hello,

If I interpret the source code in drivers/infiniband/core/cm.c correctly
ib_destroy_cm_id() can return before an ongoing cm_id callback has
finished. Is this on purpose ? If not, isn't there a
flush_workqueue(cm.wq) call missing in cm_destroy_id() ?

Thanks,

Bart.
