It does not have anything to do with this in scsi_io_completion does it?

        if (blk_complete_barrier_rq(q, req, good_bytes >> 9))

For that case the scsi_cmnd does not get freed. Does it come back around again and get released from a different path?


It looks such a likely candidate, doesn't it.  Unfortunately, Tejun Heo
removed that code around 6 Jan (in [BLOCK] update SCSI to use new
blk_ordered for barriers), so if it is that, then the latest kernels
should now not be leaking.


Oh, I thought the reports were for 2.6.15 and below which has that scsi_io_completion test. Have there been reports for this with 2.6.16-rc1 too?
