Please don't send cover letters for single patches, if there is anything that needs saying put it in the changelog of the patch or after the --- if it's administrative stuff. This reduces mail volume and ensures that any important information is recorded in the changelog rather than being lost. [unhandled content-type:application/pgp-signature] | |
