Subject: deadlock happen on p_rb_hash[i].p_lock.lock

Hi all
       I met a deadlock issue, p_rb_hash[i].p_lock.lock is not unlocked. lkrg version is 0.8,  software is android  10 ,hardware is unisoc SL8541E。
 fellow picture is trace32 stack callback and register。
 1：cpu 0




2：cpu1
3：cpu 2
4：cpu3 


     Above situation,I think where use read_lock for p_rb_hash[i].p_lock.lock ,but not unlock.Or after lock,there is some code may cause schedule. Go throuh lkrg code, I can not find this situation code.
Repeating this issue need at least two weeks. 
    Have anybody met this similar issue??


thanks and best regards
ethan
