David Miller 8871a0eaa9 Unaligned access fixes 
The first problem is that these SETGET macros lose typing information,
and therefore can't see the 'packed' attribute and therefore take
unaligned access SIGBUS signals on sparc64 when trying to derefernce
the member.

The next problem is a similar issue in btrfs_name_hash().  This gets
passed things like &key.offset which is a member of a packed
structure, losing this packed'ness information btrfs_name_hash()
performs a potentially unaligned memory access, again resulting in a
SIGBUS.

Josef Bacik ffaff17911 btrfs-progs support for root block accounting 
This adds support for keeping track of the number of blocks used by
root_item's.  This makes it so that mkfs lays down the "default" subvol with
the correct block accounting in place.  Thank you,
