aoe: add debugfs-based export of debug counters

This patch series applies to today's linux-next/akpm, commit 0c2f52fa9a7cb139617078568c48026c49927617.

It adds the debugging information that the coraid.com-distributed aoe driver exports via sysfs, but instead of sysfs, it uses debugfs.

With these patches applied, even without AoE targets on the network, KEDR reports new possible memory leaks, but these are from callers outside the aoe driver that have used aoe_devnode to get the name of the character devices through the aoe_class->devnode callback, and I believe they're responsible for freeing that memory.

Ed L. Cashin (6):
aoe: create and destroy debugfs directory for aoe
aoe: add AoE-target files to debugfs
aoe: provide file operations for debugfs files
aoe: fill in per-AoE-target information for debugfs file
aoe: update copyright date
aoe: update internal version number to 85
