xfs: enable in-core block reservation for rt metadata [v6.2 03/14]

In preparation for adding reverse mapping and refcounting to the
realtime device, enhance the metadir code to reserve free space for
btree shape changes as delayed allocation blocks.

This enables us to pre-allocate space for the rmap and refcount btrees
in the same manner as we do for the data device counterparts, which is
how we avoid ENOSPC failures when space is low but we've already
committed to a COW operation.

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

xfs: allow inode-based btrees to reserve space in the data device

Create a new space reservation scheme so that btree metadata for the
realtime volume can reserve space in the data device to avoid space
underruns.

Back when we were testing the rmap and refcount btrees for the data
device, people observed occasional shutdowns when xfs_btree_split was
called for either of those two btrees. This happened when certain
operations (mostly writeback ioends) created new rmap or refcount
records, which would expand the size of the btree. If there were no
free blocks available the allocation would fail and the split would shut
down the filesystem.

I considered pre-reserving blocks for btree expansion at the time of a
write() call, but there wasn't any good way to attach the reservations
to an inode and keep them there all the way to ioend processing. Unlike
delalloc reservations which have that indlen mechanism, there's no way
to do that for mapped extents; and indlen blocks are given back during
the delalloc -> unwritten transition.

The solution was to reserve sufficient blocks for rmap/refcount btree
expansion at mount time. This is what the XFS_AG_RESV_* flags provide;
any expansion of those two btrees can come from the pre-reserved space.

This patch brings that pre-reservation ability to inode-rooted btrees so
that the rt rmap and refcount btrees can also save room for future
expansion.

xfs: metadata inode directory trees [v5.5 03/10]

This series delivers a new feature -- metadata inode directories. This
is a separate directory tree (rooted in the superblock) that contains
only inodes that contain filesystem metadata. Different metadata
objects can be looked up with regular paths.

Start by creating xfs_imeta{dir,file}* functions to mediate access to
the metadata directory tree. By the end of this mega series, all
existing metadata inodes (rt+quota) will use this directory tree instead
of the superblock.

Next, define the metadir on-disk format, which consists of marking
inodes with a new iflag that says they're metadata. This prevents
bulkstat and friends from ever getting their hands on fs metadata files.

With a bit of luck, this should all go splendidly.
