[GIT PULL] Btrfs fixes and improvements for 4.11

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

Hi Chris.

Please consider the following changes for the 4.11 merge window.
This time there is nothing particularly outstanding when compared to the
usual set of bug fixes. These are mostly fixes for send and the no-holes
feature introduced in 3.14. Test cases for fstests were sent for half of
these changes, with some already merged and two not yet merged.

Thanks.

The following changes since commit 6e78b3f7a193546b1c00a6d084596e774f147169:
