commit b8dc7d0eea5a7709bb534f1b3ca70d2d7de0b42c introduced IPA_STATUS_SIZE as a replacement for the size of the removed struct ipa_status. sizeof(struct ipa_status) was sizeof(__le32[8]), use this as IPA_STATUS_SIZE.This is better, however it really isn't done in a way that's appropriate for a Linux kernel patch. I will gladly help you get it right if you have the patience for that. But I'm not going to say anything yet--until you say you want me to help you do this. If you prefer, I can submit the patch for you. The reason this is important is your commit is permanent, and just like code, commit messages are best if kept consistent and readable. I also am offering to help you understand so you avoid any trouble next time you want to send a kernel patch. Let me know what you prefer. -Alexquoted

So here's v3 of the patch, done (I hope) in a way that is more standard conforming.

Use this value as IPA_STATUS_SIZE. Signed-off-by: Bert Karwatzki <redacted>
This is better, but there are a few more things to do differently.
- When re-submitting a patch, please indicate a (new) version in
the subject line. Since you haven't been doing that, it should
be sufficient to just use "version 2", something like this:
[PATCH net v2] net: ipa: Use the correct value for IPA_STATUS_SIZE
- Add a "Fixes" tag above your "Signed-off-by:" line:
Fixes: b8dc7d0eea5a ("net: ipa: stop using sizeof(status)")
- Do not send information above the patch in the e-mail. An easy
way to get it right is to use "git send-email". For example:
- git format-patch -1
- Edit 0001-*.patch, adding lines like this below the "From:" line:
To: davem@davemloft.net
To: edumazet@google.com
To: kuba@kernel.org
To: pabeni@redhat.com
Cc: elder@kernel.org
Cc: netdev@vger.kernel.org
Cc: linux-arm-msm@vger.kernel.org
Cc: linux-kernel@vger.kernel.org
- Run this:
git send-email --dry-run 0001-*.patch
to try to catch any errors
- Finally, run this:
git send-email 0001-*.patch
to actually send the patch. This will require a password.
Even if you don't use "git send-email", just let the e-mail
itself indicate the "From:" and "Subject:" lines. And have
the content of the e-mail be the patch itself.
I hope this helps.
