# Samba 4.22+ enables SMB3 directory leases by default, allowing clients
# to cache directory listings locally. When files are created locally on
# the server (bypassing Samba), these cached listings go stale because
# kernel oplocks — the mechanism that would break leases on local
# changes — is incompatible with smb2 leases. Enabling kernel oplocks
# would fix this but forces Samba to disable smb2 leases, durable
# handles, and level2 oplocks, losing handle caching performance.
