Subject: [PATCH] net/mlx5: fix the unlock mismatch issue
Date: Sat, 4 Nov 2023 12:07:33 +0800 [thread overview]
Message-ID: <tencent_D1651EC7D3B588081DFD6FF1112691E61807@qq.com> (raw)
The 'need_lock' parameter controls whether the function acquires and
releases the spinlock, but the first unlock operation occurs regardless
of the 'need_lock' parameter.
To fix this issue, the spin unlock operation should be invoked within
an 'if (need_lock)' block, ensuring that the function only unlocks the
spinlock if it has previously been acquired.
Fixes: 48fbb0e93d06 ("net/mlx5: support flow meter mark indirect action with HWS")
