Pull fscache updates from David Howells:
"Preparatory work for the fscache rewrite that's being worked on and
fix some bugs. These include:
- Always select netfs stats when enabling fscache stats since they're
displayed through the same procfile.
- Add a cookie debug ID that can be used in tracepoints instead of a
pointer and cache it in the netfs_cache_resources struct rather
than in the netfs_read_request struct to make it more available.
- Use file_inode() in cachefiles rather than dereferencing
file->f_inode directly.
- Provide a procfile to display fscache cookies.
- Remove the fscache and cachefiles histogram procfiles.
- Remove the fscache object list procfile.
- Avoid using %p in fscache and cachefiles as the value is hashed and
not comparable to the register dump in an oops trace.
- Fix the cookie hash function to actually achieve useful dispersion.
- Fix fscache_cookie_put() so that it doesn't dereference the cookie
pointer in the tracepoint after the refcount has been decremented
(we're only allowed to do that if we decremented it to zero).
- Use refcount_t rather than atomic_t for the fscache_cookie
refcount"
