Subject: [PATCH ] Staging: hv: Hyper-V driver cleanup
This patch cleans up (a lot of the) naming issues that
various reviewers have noted. It also gets rid of
some unnecessary layering in the code. At the lowest
level, we have one abstraction for representing
a hyperv device (struct hyperv_device) and one
abstraction for representing a hyperv driver
(struct hyperv_driver). This collapses an unnecessary
layering that existed in the code for historical reasons.
While the patch is large, it was generated by a very
mechanical process (global search and replace). The code
compiles cleanly and I have tested this code on a 2.6.38
kernel.
