I wonder if a comment here wouldn't be helpful in the future, like: /* ext list modification counter */
It's just a suggestion though, any way you can add:
Reviewed-by: Carlos Maiolino <cmaiolino@redhat.com>
> struct xfs_btree_block *if_broot; /* file's incore btree root */
> short if_broot_bytes; /* bytes allocated for root */
> unsigned char if_flags; /* per-fork flags */
