When afs_lookup() is called, prospectively look up the next 50 uncached fids also from that same directory and cache the results, rather than just looking up the one file requested. This allows us to use the FS.InlineBulkStatus RPC op to increase efficiency by fetching up to 50 file statuses at a time. Signed-off-by: David Howells <dhowells@redhat.com>
