io_uring stable addition

by Jens Axboe

Hi, We have an issue with drains not working due to missing copy of some state, it's affecting 5.2/5.3/5.4. I'm attaching the patch for 5.4, however the patch should apply to 5.2 and 5.3 as well by just removing the last hunk. The last hunk is touching the linked code, which was introduced with 5.4. Can we get this queued up for stable? Thanks! Don't have an email for Tomáš, assuming the reported-by is fine with just his name. Want to ensure I include attribution I do have. From: Jens Axboe <axboe(a)kernel.dk> Subject: [PATCH] io_uring: ensure req->submit is copied when req is deferred There's an issue with deferred requests through drain, where if we do need to defer, we're not copying over the sqe_submit state correctly. This can result in using uninitialized data when we then later go and submit the deferred request, like this check in __io_submit_sqe(): if (unlikely(s->index >= ctx->sq_entries)) return -EINVAL; with 's' being uninitialized, we can randomly fail this check. Fix this by copying sqe_submit state when we defer a request.

MAINTAINERS updates in stable trees

by Sasha Levin

I just saw an update to the MAINTAINERS file fly by on stable@ and figured we might want to be grabbing all of those into our stable trees? Unlike documentation, it's not something the case that it can diverge from the code, and it's also very unlikely that someone wants to keep recieving mails as a result of someone who runs get_maintainers.pl on older kernels after he has removed his name upstream. Any objections to taking these updates? It'll grow our patch count, but that's one of the rare cases where I don't see a way for it to cause regressions... -- Thanks, Sasha

Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running are marked with ⏱. Reports for non-upstream kernels have a Beaker recipe linked to next to each host.
