[ion] 22748: - Add some more functions that just build IRPs to send to devices into iofunc.c from vpb.c - Add IoCheckQuerySetvolumeInformation to util.c from vpb.c with other similar functions - Add the actual VPB functions in vpc.c to fs.c, and rename fs.c to volume.c, because it already contained Volume APIs, and now with VPB, even more so. It also still contains the FileSystem stuff, which is of course also generically part of "volumes". - Delete vpb.c, rename fs.c to volume.c.
