From 89dac7bb3b0494685241369951f95494e86ee61f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 13 Nov 2014 12:42:04 +0100 Subject: lpfc: remove queue_depth events James Smart said the userspace to consume these events never emerged. Given that these get in the way of the following patches remove support for them.
