mmh.. a forward declaration of rb_root in fs.h shouldn't be better than
this?
Forward declaration works if the type was struct rb_root *. But the type
in your patch was a struct and the compiler can't figure out its size.
include/linux/fs.h:659:17: error: field ‘nocache_tree’ has incomplete type
Did you mean forward declaring struct rb_node instead of rb_root?
If we go down this path, a few more places need fixups (I ignored the
compiler warnings about casting void * to struct rb_root *).
