Again: Posting such a patch on [email protected] is ENOUGH!
No need to cross post such a patch additionally on
[email protected]
[email protected]
[email protected]
and to each of the maintainers
[email protected]
[email protected]
[email protected]
We all subscribed the mailing list and listen to it.
That's the intention of a mailing list ...
Cross posting is not appreciated in the community.
Thanks,
Oliver
