2009-01-13[SCSI] Skip deleted devices in __scsi_device_lookup_by_target()Hannes Reinecke
__scsi_device_lookup_by_target() will always return the first sdev with a matching LUN, regardless of the state. However, when this sdev is in SDEV_DEL scsi_device_lookup_by_target() will ignore this device and so any valid device on the list after the deleted device will never be found. So we have to modify __scsi_device_lookup_by_target() to skip any device in SDEV_DEL.

Here's > a snippet of a READ_10 scsi_cmnd upon completion by the storage The problem is caused by: commit b60af5b0adf0da24c673598c8d3fb4d4189a15ce Author: Alan Stern <stern@rowland.harvard.edu> Date: Mon Nov 3 15:56:47 2008 -0500 [SCSI] simplify scsi_io_completion() Because scsi_release_buffers() is called before commands that go through the ACTION_RETRY and ACTION_DELAYED_RETRY legs are requeued. However, they're not re-prepared, so nothing ever reallocates the buffer resources to them. Fix this by releasing the buffers only if we're not going to go down these legs (but scsi_release_buffers() on all legs including two in scsi_end_request(); this latter needs a special version __scsi_release_buffers() because the final one can be called after the request has been freed, so the bidi test in scsi_release_buffers(), which touches the request has to be skipped).

2009-01-05[SCSI] scsi_lib: don't decrement busy counters when inserting commandsJames Bottomley
A bug was introduced by commit b60af5b0adf0da24c673598c8d3fb4d4189a15ce Author: Alan Stern <stern@rowland.harvard.edu> Date: Mon Nov 3 15:56:47 2008 -0500 [SCSI] simplify scsi_io_completion() because the simplification uses scsi_queue_insert(). The problem with this function is that it expects to be called from the completion path while the command is still outstanding, so it decrements the device and host busy counts to do the requeue. The problem is that scsi_io_completion() is a path executed well after these counts have *already* been decremented, leading to a double decrement if the command goes down any error path leading to ACTION_DELAYED_RETRY. The fix is to allow a private function __scsi_queue_insert() with a flag to say whether the busy counters should be decremented. This is made static to scsi_lib.c to discourage other use.
