Subject: [PATCH 0/3] SPDX to btrfs

Switch fs/btrfs/*.[ch] and fs/btrfs/tests/*.[ch] to SPDX. I've briefly
verified that there are no exceptions to GPL-2.0 (ie. no 'or later').
The changes match what I've seen in other patches and I don't think
ther's more needed to be done. If there are no objections I'm going to
add the patches to a 4.17 pull.

David Sterba (3):
btrfs: replace GPL boilerplate by SPDX -- headers
btrfs: replace GPL boilerplate by SPDX -- sources

Subject: [PATCH 1/3] btrfs: replace GPL boilerplate by SPDX -- headers

Remove GPL boilerplate text (long, short, one-line) and keep the rest,
ie. personal, company or original source copyright statements. Add the
SPDX header.

Unify the include protection macros to match the file names.
