At the moment alloc_reserved_tree_block takes 8 friggin arguments. The irony is that all of those are really derived from 3 structures. This series ends up reducing the arguments to 3. As a result some code, private to alloc_reserved_tree_block is moved from run_delayed_tree_ref. Patch 1 removes the fs_info argument, Patch 2 replaces all arguments derived from btrfs_delayed_ref_node with the nodes itself, Patch 3 replaces the last 2 arguments with btrfs_delayed_extent_op and finally, Patch 4 simplifies the code a bit by removing one extra check.
All in all this doesn't provide any functional changes but makes the code easier to follow. Also it has survived 2 xfstest runs.
