how to let `submit_and_wait` to wait for a new entry about io-uring HOT 5 CLOSED

but Openat2 doesn't work, the submit_and_wait still blocking even the file is created.

I failed to reproduce this problem. can you share your code?

from io-uring.

@quininer

open_options.rs: https://fars.ee/0plu/
lib.rs: https://fars.ee/JV4i/
ext.rs: https://fars.ee/Kguw/
Cargo.toml https://fars.ee/xXlP/

the tests::open run won't finish because ring.submit_and_wait(1).unwrap(); never return

other tests work well

my kernel is 5.6.10-arch1-1, it should support Openat2

from io-uring.

run cargo test with --nocapture, the tests::open will print some log like

    Finished test [unoptimized + debuginfo] target(s) in 0.07s
     Running target/debug/deps/ring_io-100c7598fff98b7a

running 1 test
dir path "/tmp/.tmpLlv2mk"
file path "/tmp/.tmpLlv2mk/test"
start create file
pushed
submited

if submit_and_wait return, it should print log wait done and the test will be finished

from io-uring.

You forgot to call init_ring in OpenFuture, which caused submit_and_wait not to be called at all.

from io-uring.

oh.... thank you to point my mistake 🤣. after call it, the tests::open works well now, problem solved

from io-uring.
