btrfs: always set extent_io_tree::inode and drop fs_info
The extent_io_tree is embedded in several structures, notably in struct btrfs_inode. The fs_info is only used for reporting errors and for reference in trace points. We can get to the pointer through the inode, but not all io trees set it. However, we always know the owner and can recognize if inode is valid. For access helpers are provided, const variant for the trace points. This reduces size of extent_io_tree by 8 bytes and following structures in turn: - btrfs_inode 1104 -> 1088 - btrfs_device 520 -> 512 - btrfs_root 1360 -> 1344 - btrfs_transaction 456 -> 440 - btrfs_fs_info 3600 -> 3592 - reloc_control 1520 -> 1512 Reviewed-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: David Sterba <dsterba@suse.com>
