[Stgt-devel] About the command execution in tgt

[Erez Zilber]

Hi,

I'm going over some of the code, and now I'm trying to understand how is
the cmd executed in the backing store. I know how it is done in kernel
space (just call scsi-ml), but I'm pretty new to userspace.

I saw that scsi_cmd_perform calls
cmd->dev->dev_type_template.ops[op].cmd_perform. I didn't find any
implementation for cmd_perform in the code. Can anyone give a brief
explanation?


Thanks,
Erez
