https://bugzilla.kernel.org/show_bug.cgi?id=220535

            Bug ID: 220535
           Summary: ext4 __jbd2_log_wait_for_space soft lockup and CPU
                    stuck for 134s
           Product: File System
           Version: 2.5
          Hardware: Intel
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: ext4
          Assignee: fs_ext4@...nel-bugs.osdl.org
          Reporter: waxihus@...il.com
        Regression: No

On a three-node storage cluster, running mdtest concurrently causes a soft
lockup that leads to node crash. 
System load averages spike to ~300–400 and heavy file I/O causes severe memory
churn. 
The issue reproduces on kernels 5.15.0-189 and 6.4, but does not occur on the
SUSE SP4 (June 2023) kernel.

mdtest command:
mpirun -np 128 --hostfile /root/mpirun-hosts  mdtest -d /cluster_test_dir/ -n
10000 -z 1 -b 10 -u -R -w 4096 -e 4096
