Yewon Choi 52287ed416 rds: introduce acquire/release ordering in acquire/release_in_xmit() ... [ Upstream commit 1422f28826d2a0c11e5240b3e951c9e214d8656e ] acquire/release_in_xmit() work as bit lock in rds_send_xmit(), so they are expected to ensure acquire/release memory ordering semantics. However, test_and_set_bit/clear_bit() don't imply such semantics, on top of this, following smp_mb__after_atomic() does not guarantee release ordering (memory barrier actually should be placed before clear_bit()). Instead, we use clear_bit_unlock/test_and_set_bit_lock() here. Fixes: 0f4b1c7e89 ("rds: fix rds_send_xmit() serialization") Fixes: 1f9ecd7eac ("RDS: Pass rds_conn_path to rds_send_xmit()") Signed-off-by: Yewon Choi <woni9911@gmail.com> Reviewed-by: Michal Kubiak <michal.kubiak@intel.com> Link: https://lore.kernel.org/r/ZfQUxnNTO9AJmzwc@libra05 Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2024-03-26 18:21:00 -04:00
