Btrfs: kill the pinned_mutex 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. Signed-off-by: Josef Bacik <jbacik@redhat.com>
