Fnic: Fnic Driver crashed with NULL pointer reference
When issuing I/O request, if the I/O completes before returning from fnic_queuecommand(), we may be referencing scsi_cmnd structure that may be freed by interrupt handler. Acquring IO lock would synchronize fnic_queuecommand and interrupt handler. - Increment fnic version from 1.6.0.15 to 1.6.0.16 Signed-off-by: NHiral Shah <hishah@cisco.com> Signed-off-by: NSesidhar Baddela <sebaddel@cisco.com> Signed-off-by: NAnil Chintalapati <achintal@cisco.com> Signed-off-by: NChristoph Hellwig <hch@lst.de>
