You could just read the xfs_growfs source and see :)

The actual resizing is performed in the kernel XFS driver and xfs_growfs
isn't doing a lot more than calling a bunch of fcntls (IRIX) or
ioctls(Linux) that perform the actual resize in a way that it is journaled
like other filesystem transactions.
