      scsi,block: update SCSI to handle mixed merge failures · da6c5c72
      由 Tejun Heo 提交于 
      Update scsi_io_completion() such that it only fails requests till the
next error boundary and retry the leftover.  This enables block layer
to merge requests with different failfast settings and still behave
correctly on errors.  Allow merge of requests of different failfast
settings.

As SCSI is currently the only subsystem which follows failfast status,
there's no need to worry about other block drivers for now.

      [SCSI] fcoe: flush per-cpu thread work when destroying interface · e7a51997
      由 Joe Eykholt 提交于 
      This fixes one cause of an occational problem when unloading
libfc where the exchange manager pool doesn't have all items freed.

The existing WARN_ON(mp->total_exches <= 0) isn't hit.
However, note that total_exches is decremented when the
exchange is completed, and it can be held with a refcnt
for a while after that.

I'm not sure what the offending exchange is, but I suspect
it is an incoming request, because outgoing state machines
should be all stopped at this point.

Note that although receive is stopped before the exchange
manager is freed, there could still be active threads
handling received frames.

This patch flushes the queues by allocating a new skb
and sending it through, and have the thread handle
this new skb specially.  This is similar to the way the work
queues are flushed now by putting work items in them and waiting
until they make it through the queue.

An skb->destructor function is used to inform us of
the completion of the flush, and the fr_dev() is left
NULL to indicate to fcoe_percpu_receive_thread() that
the skb should be just freed.  There's already a check
for the lp being NULL which prints a message.
We skip printing the message if the destructor is for flushing.

      [SCSI] libfc: don't swap OX_ID and RX_ID when sending BA_RJT · 1d490ce3
      由 Joe Eykholt 提交于 
      I saw an lport debug message from the exchange manager saying:
"lport  70500: Received response for out of range oxid:ffff"

A trace showed this was a BA_RJT sent due to an incoming ABTS
which arrived on an unknown exchange.  So, the sender of the
BA_RJT was in error, but in this case, both the initiator and
responder were the same machine.

The OX_ID and RX_ID should not have been reversed in this case.
