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.
