I have to admit I never understood the purpose of this call.
What xfs_fstrm_free_func does is:
- clear the filesystems flag on the inode
- decrement pagf_fstrms
- drop references on the inode (and parent if known)
- free the filestream item
Nothing of that should matter for sync, although dropping inode
references during sync might generally be a good idea.
