Subject: bug report about assert at [ kernel/fs/jbd2/transaction.c:2138 ]

Hi  

I have a crash on Android phone during daily use.

It crash at function __jbd2_journal_refile_buffer( ) :

if (jh->b_transaction)
		assert_spin_locked(&jh->b_transaction->t_journal->j_list_lock);


I have a look at the code,
Seems this part are all handled by kernel ,
So should be kernel BUG ,

https://www.codeaurora.org/cgit/quic/la/kernel/msm/tree/fs/jbd2/commit.c?id=ccde7494b7174d810f316019b6e935fb222c6533

the kernel that we use ,
could someone can have a look at this part ?
I am not very clear about this part .


Thanks
