Hi Qian,
Thanks for response!
Could you like just try to revert the patch: 'mm/thp: narrow lru locking'? or would you like to
share me info of your tests and let me reproduce it? like kernel config, system ENV, machine type.
I had run hundreds cycle of oom01, but akpm kernel(f2cbd107a99b) still survived.
I got my ltp mm testing results, it run total 75 cases, failed 2, skip 9 and others are success
and kernel works well after test on yesterday's akmp head: f2cbd107a99b.
Many Thanks for help!
Alex
