Mark FashehandZach Brown c0d3f99a6e scoutfs: Cluster coherent read/write ...

With trylock implemented we can add locking in readpage. After that it's
pretty easy to implement our own read/write functions which at this
point are more or less wrapping the kernel helpers in the correct
cluster locking.

Data invalidation is a bit interesting. If the lock we are invalidating
is an inode group lock, we use the lock boundaries to incrementally
search our inode cache. When an inode struct is found, we sync and
(optionally) truncate pages.
