Description Mike Christie 2005-06-15 18:44:37 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
scsi_dispatch_cmd currently calls scsi_done when the device is in the
SDEV_DEL state, but at this point the command has not had a timer added
to it (this is done a couple lines down) so scsi_done just returns and
the command is lost. The attached patch made against the current RHEL4
kernel calls __scsi_done in this case so the comamnd will be returned upwards.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. run IO
2. remove a scsi host (like usb-mass-storage or iscsi-sfnet)
3. commands are lost
