Subject: [Stgt-devel] [PATCH] add stgt_device_template example
Date: Tue, 23 Aug 2005 00:59:16 -0500

> This adds the beginings of a stgt_device_template for
> passthrough commands. It will end up using the block
> layer BLOCK_PC facility to pass the command to the
> underlying device similar to how we do it for SG_IO
> and dm-multipath hw_handlers like dm-emc.c.
> It is not completely hooked in yet. The command
> handling needs to be done and so does the actual
> device creation.
> This was built over my last patch.
