HI,
For SRIOV support, currently in the KVM environment, mpt3sas driver
can use the API pci_vfs_assigned() to know the number of VFs that are
currently assigned to the running VMs. So that during the PF driver

Then, Is there any other ways to stop accidental unload of PF driver

The check of SCF_SCSI_DATA_CDB seems to be a remnant from before hch's
refactoring of this function. There are no places where that flag is set
that cmd-execute_cmd isn't also set.

In order to prevent a O(n) search of the filesystem to link up its uio
node with its target configuration, TCMU needs to know the minor number
that UIO assigned. Expose the definition of this struct so TCMU can
access this field.

Hi all,
Here is version two of the userspace passthrough backstore code I've
been working on.
You can find some documentation on the design in last patch. Please
let me know what you think about the design and the code.
Thanks -- Andy
Changes since version 1:
* Use netlink for reporting device
Add a LIO storage engine that presents commands to userspace for execution.
This would allow more complex backstores to be implemented out-of-kernel,
and also make experimentation a-la FUSE (but at the SCSI level -- SUSE?)
possible.
It uses a mmap()able UIO device per LUN to share a command ring
Describes the driver and its interface to make it possible for user
programs to back a LIO-exported LUN.
