Regression test for adding and dropping an equal number of references for file extents. Verify that if we drop N references for a file extent and we add too N new references for that same file extent in the same transaction, running the delayed references (which always happens at transaction commit time) does not fail. The regression was introduced in the 4.2-rc1 Linux kernel and fixed by the patch titled: "Btrfs: fix order by which delayed references are run".
