^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) * For balance, we need to swap subtree of subvolume and reloc trees.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) * In theory, we need to trace all subtree blocks of both subvolume and reloc

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) * However since balance has ensured that both subtrees are containing the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) * same contents and have the same tree structures, such swap won't cause

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) * But there is a race window between subtree swap and transaction commit,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) * during that window, if we increase/decrease tree level or merge/split tree
