Subject: Re: "Btrfs: device_list_add() should not update list when mounted" breaks subvol mount

Hi,

On standard ubuntu 14.04 a with an encrypted (cryptsetup) /home as brtfs 
subvolume we have the following results:
3.17-rc2 : Ok.
3.17-rc3 and 3.17-rc4 :  /home fails to mount on boot. If one try mount 
-a then the system tells that the partition is already mounted according 
to matab.


On a 3.17-rc4, btrfs fi sh returns nothing special:
"
Label: none  uuid: f4f554bb-57d9-4647-ab14-ea978c9e7e9f
         Total devices 1 FS bytes used 131.41GiB
         devid    1 size 173.31GiB used 134.03GiB path /dev/sda5

Btrfs v3.12
"

I'm not sure if it has something to do with cryptsetup...
