xfs: reflink on the realtime device [v6.2 05/14]

This patchset enables use of the file data block sharing feature (i.e.
reflink) on the realtime device. It follows the same basic sequence as
the realtime rmap series -- first a few cleanups; then introduction of
the new btree format and inode fork format. Next comes enabling CoW and
remapping for the rt device; new scrub, repair, and health reporting
code; and at the end we implement some code to lengthen write requests
so that rt extents are always CoWed fully.

This has been running on the djcloud for months with no problems. Enjoy!

xfs: realtime reverse-mapping support [v6.2 04/14]

This is the latest revision of a patchset that adds to XFS kernel
support for reverse mapping for the realtime device. This time around
I've fixed some of the bitrot that I've noticed over the past few
months, and most notably have converted rtrmapbt to use the metadata
inode directory feature instead of burning more space in the superblock.

At the beginning of the set are patches to implement storing B+tree
leaves in an inode root, since the realtime rmapbt is rooted in an
inode, unlike the regular rmapbt which is rooted in an AG block.
Prior to this, the only btree that could be rooted in the inode fork
was the block mapping btree; if all the extent records fit in the
inode, format would be switched from 'btree' to 'extents'.

The next few patches enhance the reverse mapping routines to handle
the parts that are specific to rtgroups -- adding the new btree type,
adding a new log intent item type, and wiring up the metadata directory
tree entries.

Finally, implement GETFSMAP with the rtrmapbt and scrub functionality
for the rtrmapbt and rtbitmap and online fsck functionality.

This has been running on the djcloud for months with no problems. Enjoy!

xfs: online repair of the realtime rmap btree

Repair the realtime rmap btree while mounted. Similar to the regular
rmap btree repair code, we walk the data fork mappings of every realtime
file in the filesystem to collect reverse-mapping records in an xfarray.
Then we sort the xfarray, and use the btree bulk loader to create a new
rtrmap btree ondisk. Finally, we swap the btree roots, and reap the old
blocks in the usual way.
