From 3a7d55c84c76a3088ddfb798c187182143683a16 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Wed, 16 Jul 2014 18:38:01 +0800 Subject: Btrfs: fix wrong missing device counter decrease The missing devices are accounted by its own fs device, for example the missing devices in seed filesystem will be accounted by the fs device of the seed filesystem, not by the new filesystem which is based on the seed filesystem, so when we remove the missing device in the seed filesystem, we should decrease the counter of its own fs device. Fix it.
