Hi,

在 2022/10/17 14:53, Ye Bin 写道:
To solve above issues, reference commit '5afedf670caf', first stop block trace
when block trace state is 'Blktrace_running' in '__blk_trace_remove'.

Will it be much simpler if we just return -EBUSY in blk_trace_remove if
state is still running?

And similar checking in blk_trace_setup.

Thanks,
Kuai
