Subject: pgsql: Convert FastPathStrongRelationLocks to atomics.
Date: Fri, 04 Sep 2026 18:03:45 +0000
Message-ID: <E1x2YGO-00000003TyJ-2aIX@gemulon.postgresql.org> (raw)

Convert FastPathStrongRelationLocks to atomics.

Currently, the lock counts are unsigned integers protected by a
spinlock.  By converting them to atomic variables, we can remove
the spinlock and the FastPathStrongRelationLockData wrapper struct.
