    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
