Hi,

Please could you rebase on master and keep the acked already given?
Please use --in-reply-to to keep v3 in the same thread as v2.

Titles are the same for every patches.
Are they all fixing a NULL pointer check and a mem leak?
More details in the commit message may help.

If they are fixes, a tag Fixes: may help for backports.

Thanks

> Hi,

Please re-send those which are not integrated yet,
with more details, and appropriate title.
Thanks
