Hello,
on the latest kernel a fio job with 4 workers using libaio hangs.
git bisect points to:
commit e02ba72aabfade4c9cd6e3263e9b57bf890ad25c

aio: block io_destroy() until all context requests are completed
The fio workers are on the wait_for_completion in sys_io_destroy.
Regards,
Sebastian[global]
