Pull Request Guidelines

1. To make everyone easily filter pull request from the email
   notification, use [GIT PULL] as a prefix in your PR title.

[GIT PULL] Your Pull Request Title

2. Follow the commit message format rules below.
3. Follow the Linux kernel coding style (see: https://github.com/torvalds/linux/blob/master/Documentation/process/coding-style.rst).

Commit message format rules:

1. The first line is title (don't be more than 72 chars if possible).
2. Then an empty line.
3. Then a description (may be omitted for truly trivial changes).
4. Then an empty line again (if it has a description).
5. Then a Signed-off-by tag with your real name and email. For example:

Signed-off-by: Foo Bar <foo.bar@gmail.com>

The description should be word-wrapped at 72 chars. Some things should
not be word-wrapped. They may be some kind of quoted text - long
compiler error messages, oops reports, Link, etc. (things that have a
certain specific format).

Note that all of this goes in the commit message, not in the pull
request text. The pull request text should introduce what this pull
request does, and each commit message should explain the rationale for
why that particular change was made. The git tree is canonical source
of truth, not github.

Each patch should do one thing, and one thing only. If you find yourself
writing an explanation for why a patch is fixing multiple issues, that's
a good indication that the change should be split into separate patches.

If the commit is a fix for an issue, add a Fixes tag with the issue
URL.

Don't use GitHub anonymous email like this as the commit author:

123456789+username@users.noreply.github.com

Use a real email address!

Commit message example:

src/queue: don't flush SQ ring for new wait interface

If we have IORING_FEAT_EXT_ARG, then timeouts are done through the
syscall instead of by posting an internal timeout. This was done
to be both more efficient, but also to enable multi-threaded use
the wait side. If we touch the SQ state by flushing it, that isn't
safe without synchronization.

Just make this:

		name = inet_ntop(ctx->af, &addr->sin_addr, buff, sizeof(buff));

as there's no need for the parenthesis in there.

Fix looks good (with cosmetic adjustment suggested), but your commit message should be better. First of all, the first line should be a title for the commit. "Update foo.c" doesn't mean anything, what is being changed here? And then the body should have an explanation of why the change is necessary. Finally, a Signed-off-by line is required with your identity (name) and email as well.

See the other commits in the repo for an example of what a commit message should look like. Here's one from Pavel:

Don't add a new commit to fix your previous unmerged commit. Just fold
it in, then force-push. It's fine to force push to your branch.

Also, as previously has been told, use a Signed-off-by with a real name
and email.

[ammarfaizi2]

I'll send a patch.
