Stefan Richter 09ee67abe9 ieee1394: sbp2: handle "sbp2util_node_write_no_wait failed" ... Fix for http://bugzilla.kernel.org/show_bug.cgi?id=6948 Because sbp2 writes to the target's fetch agent's registers from within atomic context, it cannot sleep to guaranteedly get a free transaction label. This may repeatedly lead to "sbp2util_node_write_no_wait failed" and consequently to SCSI command abortion after timeout. A likely cause is that many queue_command softirqs may occur before khpsbpkt (the ieee1394 driver's thread which cleans up after finished transactions) is woken up to recycle tlabels. Sbp2 now schedules a workqueue job whenever sbp2_link_orb_command fails in sbp2util_node_write_no_wait. The job will reliably get a transaction label because it can sleep. We use the kernel-wide shared workqueue because it is unlikely that the job itself actually needs to sleep. In the improbable case that it has to sleep, it doesn't need to sleep long since the standard transaction timeout is 100ms.
