Hi,
The following setting maybe useful to diag the data flush problem inside btrfs.
# we need SSD for this test case
vm.dirty_expire_centisecs = 200
vm.dirty_writeback_centisecs = 100
kernel.hung_task_timeout_secs=4
kernel.hung_task_all_cpu_backtrace=1
In fact, only few cases of high load was reported.
but some case of btrfs-cleaner when low load is reported too.
it maybe an issue inside btrfs, or expected behavor?

This is the cause, qgroup.
And you mentioned cleaner kthread, are you dropping some large shared
snapshots?
If so, no wonder.
In that case, you'd better config
/sys/fs/btrfs/<uuid>/qgroups/drop_subtree_threshold to some lower value,
e.g. 3, to prevent the problem.
Thanks,

the snapshot drop should be triggered by snapper timeline cleanup.
Could we do some schedule change inside btrfs to slicence it?
