[PATCH] Change occurences of netapp to ontap.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ritesh Raj Sarraf <rrs@xxxxxxxxxxxxxx>

Change all occurences of netapp to ontap to be consistent.
This was proposed earlier, before the libprio change, but was deferred for
compatibility reasons.

Also update maintainers.
