maybe I don't think the below patch completely fix this issue, as I
found a new error(maybe similar with this):

it's easy to reproduce with stress[1] workload.
what command I used is '# stress -i 20 -m 30 -v'
I will report it on a new subject if it's a new issue.
let me know if you need other info.
