Hi,
I think I've made a bad assumption over my usage of radix_tree_tag_get() in fs/fscache/page.c.
I've assumed that radix_tree_tag_get() is protected from radix_tree_tag_set() and radix_tree_tag_clear() by the RCU read lock. However, now I'm not so sure. I think it's only protected against removal of part of the tree.
Can you confirm?
David
