fs: port inode_init_owner() to mnt_idmap
Convert to struct mnt_idmap.
Last cycle we merged the necessary infrastructure in 256c8aed2b42 ("fs: introduce dedicated idmap type for mounts"). This is just the conversion to struct mnt_idmap.
Currently we still pass around the plain namespace that was attached to a mount. This is in general pretty convenient but it makes it easy to conflate namespaces that are relevant on the filesystem with namespaces that are relevent on the mount level. Especially for non-vfs developers without detailed knowledge in this area this can be a potential source for bugs.
Once the conversion to struct mnt_idmap is done all helpers down to the really low-level helpers will take a struct mnt_idmap argument instead of two namespace arguments. This way it becomes impossible to conflate the two eliminating the possibility of any bugs. All of the vfs and all filesystems only operate on struct mnt_idmap.

btrfs: add optimized btrfs_ino() version for 64 bits systems
Currently btrfs_ino() tries to use first the objectid of the inode's location key. This is to avoid truncation of the inode number on 32 bits platforms because the i_ino field of struct inode has the unsigned long type, while the objectid is a 64 bits unsigned type (u64) on every system. This logic was added in commit 33345d01522f81 ("Btrfs: Always use 64bit inode number").
However if we are running on a 64 bits system, we can always directly return the i_ino value from struct inode, which eliminates the need for he special if statement that tests for a location key type of BTRFS_ROOT_ITEM_KEY - in which case i_ino may not have the same value as the objectid in the inode's location objectid, it may have a value of BTRFS_EMPTY_SUBVOL_DIR_OBJECTID, for the case of snapshots of trees with subvolumes/snapshots inside them.
So add a special version for 64 bits system that directly returns i_ino of struct inode. This eliminates one branch and reduces the overall code size, since btrfs_ino() is an inline function that is extensively used.

Revert the xarray conversion, there's a problem with potential sleep-inside-spinlock [1] when calling xa_insert that triggers GFP_NOFS allocation. The radix tree used the preloading mechanism to avoid sleeping but this is not available in xarray.
Conversion from spin lock to mutex is possible but at time of rc6 is riskier than a clean revert.

btrfs: track the csum, extent, and free space trees in a rb tree
In the future we are going to have multiple copies of these trees. To facilitate this we need a way to lookup the different roots we are looking for. Handle this by adding a global root rb tree that is indexed on the root->root_key. Then instead of loading the roots at mount time with individually targeted keys, simply search the tree_root for anything with the specific objectid we want. This will make it straightforward to support both old style and new style file systems.

btrfs: selftests: fix wrong error check in btrfs_free_dummy_root()
commit 9b2f20344d450137d015b380ff0c2e2a6a170135 upstream.
The btrfs_alloc_dummy_root() uses ERR_PTR as the error return value rather than NULL, if error happened, there will be a NULL pointer dereference:

btrfs: selftests: fix wrong error check in btrfs_free_dummy_root()
commit 9b2f20344d450137d015b380ff0c2e2a6a170135 upstream.
The btrfs_alloc_dummy_root() uses ERR_PTR as the error return value rather than NULL, if error happened, there will be a NULL pointer dereference:
