Nginx Double aio bug on NGINX_IOURING_PATCH='y'

Please fill in any relevant information that applies to you:

• CentOS Version: 7.7 64bit

  NGINX_IOURING_PATCH='y'

I have tried this more than 10 times. Whenever I compile nginx via option 4 on centmin after inserting NGINX_IOURING_PATCH='y' then it gets stuck at the last process of some kill switch. Then after reconnecting SSH, I run

Code:

nginx -t

it shows nginx: [emerg] "aio" directive is duplicate in /usr/local/nginx/conf/nginx.conf:102. Then I have to comment out the other aio on. It looks like this

Code:

sendfile off;
aio on;
#aio on;
sendfile_max_chunk 512k;

After this everything gets normal. Is this normal or is it conflicting with something from my customconfig file??

My Linux Kernel version is 5.5.9-1.el7.elrepo.x86_64. I knew the minimum requirement so I have already upgraded to latest version but when I compile nginx by NGINX_IOURING_PATCH='y' then it puts two aio on in nginxconf by itself and I need to manually comment out one aio on and it starts working.
