[PULL] Btrfs, recent cleanup patches

[PULL] Btrfs, recent cleanup patches

[David Sterba]

Hi,

I've collected the cleanup patches that are not in the integration
branch, the time span is last few months. I've reviewed them but tested
only lightly due to yet unknown problems in the current integration branch.

The target release is probably 3.21, I'm going to send more cleanup
series so that can be a base for next development cycle and minize
conflicts with other changes.

Please pull, thanks.
