afs_do_lookup() will do an order-1 allocation to allocate status records if there are more than 39 vnodes to stat. Fix this by allocating an array of {status,callback} records for each vnode we want to examine using vmalloc() if larger than a page. This not only gets rid of the order-1 allocation, but makes it easier to grow beyond 50 records for YFS servers. It also allows us to move to {status,callback} tuples for other calls too and makes it easier to lock across the application of the status and the callback to the vnode. Fixes: 5cf9dd55 ("afs: Prospectively look up extra files when doing a single lookup") Signed-off-by:
