From: Li Qiang Date: Wed, 23 Nov 2016 13:53:34 +0100 Subject: [PATCH] 9pfs: add cleanup operation for proxy backend driver In the init operation of proxy backend dirver, it allocates a V9fsProxy struct and some other resources. We should free these resources when the 9pfs device is unrealized. This is what this patch does.
