SubjectAn incorrect assumption over radix_tree_tag_get()
Date

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
