WARNING: possible circular locking dependency detected
6.2.0-rc8-next-20230220 #1 Not tainted
------------------------------------------------------
syz-executor.7/74844 is trying to acquire lock:
ffff88800ffd0170 (&journal->j_barrier){+.+.}-{3:3}, at: jbd2_journal_lock_updates+0x162/0x310

but task is already holding lock:
ffff88800ff4eb90 (&sbi->s_writepages_rwsem){++++}-{0:0}, at: ext4_change_inode_journal_flag+0x17f/0x550

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Chain exists of:
  &journal->j_barrier --> &sb->s_type->i_mutex_key#6 --> &sbi->s_writepages_rwsem

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&sbi->s_writepages_rwsem);
                               lock(&sb->s_type->i_mutex_key#6);
                               lock(&sbi->s_writepages_rwsem);
  lock(&journal->j_barrier);
