    Btrfs: kill the pinned_mutex · 04018de5

    This patch removes the pinned_mutex.  The extent io map has an internal tree
    lock that protects the tree itself, and since we only copy the extent io map
    when we are committing the transaction we don't need it there.  We also don't
    need it when caching the block group since searching through the tree is also
    protected by the internal map spin lock.
