I'm investigating this. Thanks for the report! > Btw., why does 46b402a0e5e4 and 563558b2c735 have the same title? Well, 46b402a0e5e4 refers to version 6 of my patchset and 563558b2c735 is a diff between version 6 and 7. I've seen from the e-mails from Andrew that I received that he added both patches and then folded the latter into the former. The same thing happened with several other patches but only these two sneaked in. Maybe this is a bug in the software (quilt?). --=20 Alexander --Sig_/RKplKHgI/hm6U8B/e827BgI Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEcBAEBCAAGBQJNODLPAAoJEElrwznyooJbMLsH/jTTRqw1wNprNVjfjRTTK3G0 ZvCuRPggegJaMVrXtuGkuhhL32Np1FyUS5EYy1aSxPEkNXRmylJunrnKBLEIxOQb an7szzbNGC+zh68nxaodAkrGtLFgs86rvDuncyn5tALzQa7okzKpXCuws/byDLmY WTII19YZ52db3NoqUmj070c/YhRB6e1+C9CPCIIHX+FIdBf5foog/vtiTyYFaXWx /IM6ABNOQX0Sx0ltdtPoLiApWy9UDsb7/Tvo8+iDsBvrKs0FxIwkNzqBLAQ7f4wz ssFeliut7lsCstq7bHlQKvYEvaGmWMf2bZlRWLfYuLQ8/cRvri8b9WAmkhq5xcA= =SVg6 -----END PGP SIGNATURE----- --Sig_/RKplKHgI/hm6U8B/e827BgI--
