Wong Add the ondisk structure definitions for realtime refcount btrees. The realtime refcount btree will be rooted from a hidden inode so it needs to have a separate btree block magic and pointer format. Next, add everything needed to read, write and manipulate refcount btree blocks. This prepares the way for connecting the btree operations implementation. Signed-off-by: "Darrick J.
