Ping.

In the past week, I spent some time on testing this patchset 
and
the patch 'btrfs: fix lockdep warning while mounting sprout 
fs'.

Same as you, I wonder if there is any race condition. Just 
wrote
some scripts including device removal, replace and sprout while
busy looping showing mount info. It runned well and passed
xfstests
in my two VMs. I'm not a pundit in btrfs device field so I 
can't
give my
RBs even these patches looks almost okay to me.

So this could be a Tested-by if you want.

Sure. Thanks.
