stable inclusion from stable-5.10.50 commit a16eae11f004fa193865f2858514996069b3fca0 bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit d04c1ff0b3ddd5c0fbbe640996c8eaad279ed1c5 ]
tuple_set_u64() produces a signed value instead of an unsigned value. That works for database export but not other cases. Rename to tuple_set_d64() for database export and fix tuple_set_u64().
