Loading files stored with lzo compression from a btrfs filesystem was
producing unaligned memory accesses, which were causing a data abort
and a reset on an Orange Pi Zero.
The change in hash.c is not triggered by any error but follows the
same pattern. Please confirm.
Fixed according to doc/README.unaligned-memory-access.txt

fs: btrfs: Add single-device read-only BTRFS implementation2017-10-03T01:52:17ZMarek Behúnmarek.behun@nic.cz2017-09-03T15:00:28Zurn:sha1:21a14facb1494592c3ad4874c6a00539d15a29cf
This adds the proper implementation for the BTRFS filesystem.
The implementation currently supports only read-only mode and
the filesystem can be only on a single device.
Checksums of data chunks is unimplemented.
Compression is implemented (ZLIB + LZO).
