Violin Memory SSD array device support

Violin Memory SSD array device support

[Sherman Ma]

  I would like to add Violin Memory's SSD array device (vtms) support in
LVM2.
The following is the change list:

sma at eng-builds-fir:~/git/lvm2/lib/filters$ git diff
diff --git a/lib/filters/device-types.h b/lib/filters/device-types.h
index 9efbe68..bc0cfc6 100644

@@ -56,5 +56,6 @@ static const device_info_t _device_info[] = {
        {"blkext", 1},          /* Extended device partitions */
        {"fio", 16},            /* Fusion */
        {"mtip32xx", 16},       /* Micron PCIe SSDs */
+       {"vtms", 16},           /* Violin Memory */
        {"", 0}
 };

Any comments before I submit the change?
Thanks,

What's the submit process via git for LVM? I tried to push
and it didn't work. Could someone help me out?

Thanks,

It's ok, to post proposal patches to the list.
Only lvm developers have 'write' access.

What is the current upstream status of the driver?

The driver (vtms.ko) has been released and is in good status.

Thanks,

Hmm - I've made grep over  3.7-rc kernel and have not noticed anything
resembling vtms name.

Which 'upstream' kernel tree do you mean ?

Any git pointer ?
Is it publicly available ?

Thanks

Hi Zdenek,

  Sorry I didn't make it clear. The driver is currently released
as a loadable module in binary format. Would that be a problem
in adding support in lvm?

  Thanks,

Are there plans to submit it to the upstream kernel?
