Currently struct btrfs_inode has a key member, named "location", that is
either:
1) The key of the inode's item. In this case the objectid is the number
of the inode;
2) A key stored in a dir entry with a type of BTRFS_ROOT_ITEM_KEY, for
the case where we have a root that is a snapshot of a subvolume that
points to other subvolumes. In this case the objectid is the ID of
a subvolume inside the snapshotted parent subvolume.
The key is only used to lookup the inode item for the first case, while
for the second it's never used since it corresponds to directory stubs
created with new_simple_dir() and which are marked as dummy, so there's
no actual inode item to ever update. In the second case we only check
the key type at btrfs_ino() for 32 bits platforms and its objectid is
only needed for unlink.
Instead of using a key we can do fine with just the objectid, since we
can generate the key whenever we need it having only the objectid, as
in all use cases the type is always BTRFS_INODE_ITEM_KEY and the offset
is always 0.
So use only an objectid instead of a full key. This reduces the size of
struct btrfs_inode from 1048 bytes down to 1040 bytes on a release kernel.

When not using the NO_HOLES feature we always allocate an io tree for an
inode's file_extent_tree. This is wasteful because that io tree is only
used for regular files, so we allocate more memory than needed for inodes
that represent directories or symlinks for example, or for inodes that
correspond to free space inodes.
So improve on this by allocating the io tree only for inodes of regular
files that are not free space inodes.

The index_cnt field of struct btrfs_inode is used only for two purposes:
1) To store the index for the next entry added to a directory;
2) For the data relocation inode to track the logical start address of the
block group currently being relocated.
For the relocation case we use index_cnt because it's not used for
anything else in the relocation use case - we could have used other fields
that are not used by relocation such as defrag_bytes, last_unlink_trans
or last_reflink_trans for example (among others).
Since the csum_bytes field is not used for directories, do the following
changes:
1) Put index_cnt and csum_bytes in a union, and index_cnt is only
initialized when the inode is a directory. The csum_bytes is only
accessed in IO paths for regular files, so we're fine here;
2) Use the defrag_bytes field for relocation, since the data relocation
inode is never used for defrag purposes. And to make the naming better,
alias it to reloc_block_group_start by using a union.
This reduces the size of struct btrfs_inode by 8 bytes in a release
kernel, from 1056 bytes down to 1048 bytes.

Currently we use the spinlock inode_lock from struct btrfs_root to
serialize access to two different data structures:
1) The delayed inodes xarray (struct btrfs_root::delayed_nodes);
2) The inodes xarray (struct btrfs_root::inodes).
Instead of using our own lock, we can use the spinlock that is part of the
xarray implementation, by using the xa_lock() and xa_unlock() APIs and
using the xarray APIs with the double underscore prefix that don't take
the xarray locks and assume the caller is using xa_lock() and xa_unlock().
So remove the spinlock inode_lock from struct btrfs_root and use the
corresponding xarray locks. This brings 2 benefits:
1) We reduce the size of struct btrfs_root, from 1336 bytes down to
1328 bytes on a 64 bits release kernel config;
2) We reduce lock contention by not using anymore the same lock for
changing two different and unrelated xarrays.

When creating a new inode, at btrfs_create_new_inode(), one of the very
last steps is to add the inode to the root's inodes xarray. This often
requires allocating memory which may fail (even though xarrays have a
dedicated kmem_cache which make it less likely to fail), and at that point
we are forced to abort the current transaction (as some, but not all, of
the inode metadata was added to its subvolume btree).
To avoid a transaction abort, preallocate memory for the xarray early at
btrfs_create_new_inode(), so that if we fail we don't need to abort the
transaction and the insertion into the xarray is guaranteed to succeed.

Currently we use a red black tree (rb-tree) to track the currently open
inodes of a root (in struct btrfs_root::inode_tree). This however is not
very efficient when the number of inodes is large since rb-trees are
binary trees. For example for 100K open inodes, the tree has a depth of
17. Besides that, inserting into the tree requires navigating through it
and pulling useless cache lines in the process since the red black tree
nodes are embedded within the btrfs inode - on the other hand, by being
embedded, it requires no extra memory allocations.
We can improve this by using an xarray instead, which is efficient when
indices are densely clustered (such as inode numbers), is more cache
friendly and behaves like a resizable array, with a much better search
and insertion complexity than a red black tree. This only has one small
disadvantage which is that insertion will sometimes require allocating
memory for the xarray - which may fail (not that often since it uses a
kmem_cache) - but on the other hand we can reduce the btrfs inode
structure size by 24 bytes (from 1080 down to 1056 bytes) after removing
the embedded red black tree node, which after the next patches will allow
to reduce the size of the structure to 1024 bytes, meaning we will be able
to store 4 inodes per 4K page instead of 3 inodes.
This change does a straightforward change to use an xarray, and results
in a transaction abort if we can't allocate memory for the xarray when
creating an inode - but the next patch changes things so that we don't
need to abort.
Running the following fs_mark test showed some improvements:
$ cat test.sh

There are several hard-to-hit ASSERT()s hit inside raid56.
Unfortunately the ASSERT() expression is a little complex, and except
the ASSERT(), there is nothing to provide any clue.
Considering if race is involved, it's pretty hard to reproduce.
Meanwhile sometimes the dump of the rbio structure can provide some
pretty good clues, it's worth to do the extra multi-line dump for
btrfs raid56 related code.
The dump looks like this:

Due to a refactoring introduced by commit 53d9981ca20e ("btrfs: split
btrfs_alloc_ordered_extent to allocation and insertion helpers"), the
function btrfs_alloc_ordered_extent() was renamed to
alloc_ordered_extent(), so the comment at btrfs_remove_ordered_extent()
is no longer very accurate. Update the comment to refer to the new
name "alloc_ordered_extent()".

The ioctls that add relations, create qgroups or set limits start/join
transaction. When quotas are not enabled this is not necessary, there
will be errors reported back anyway but this could be also misleading
and we should really report that quotas are not enabled. For that use
-ENOTCONN.
The helper is meant to do a quick check before any other standard ioctl
checks are done. If quota is disabled meanwhile we still rely on proper
locking inside any active operation changing the qgroup structures.
