Well, we're caught in the "no dead code" rule trap. Can't merge the UET code because it has no consumer, and can't merge ours without it as a consumer, so I have to make my branch based on their branch, and their merge base went away. They'll have to rebase and then I'll have to rebase on theirs again. But I expected a v3 for their code anyway, so just whenever Eric gets around to fixing the Sashiko findings and posting v3, I can rebase on that, and then the sashiko prompts can be run. But, FWIW, since the rdma portion of our submission was all brand new code, it passed checkpatch and sashiko on our end. It's the existing code in the netdev tree that's where all the fun will be :-/. --=20 Doug Ledford GPG KeyID: B826A3330E572FDD Key fingerprint =3D AE6B 1BDA 122B 23B4 265B 1274 B826 A333 0E57 2FD= D --------------K642xjH2taC5hBn5cbWYdFC2-- --------------85ngTJZ6nDGGF0DAemINvGcg Content-Type: application/pgp-signature; name="OpenPGP_signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="OpenPGP_signature.asc" -----BEGIN PGP SIGNATURE----- wsF5BAABCAAjFiEErmsb2hIrI7QmWxJ0uCajMw5XL90FAmrrWpIFAwAAAAAACgkQuCajMw5XL93O 8Q//Yf7qiD0+0hA0Ie4KpjySzmh+/DnLmSkm7vzKxLbuJPNGua81D1eyrK2LfgTRTH1vNC8c6GWx wZaSN5zTmcAmwGbDgyVfctrOBEfGxgVB42iPjZrtvaXWDbqEPjAxM44rOType5v9o0BaYyxwa18r nfsW/6+GkJFnAOUVozvI7LoeelrPIoluBsR9qHEP3evR/OOl5r/1V7HER25wP6tg9o7+jG6LuRL6 9vbq72b6gX3H7se0Fag1pCR5tVOjp4vbEqwk4vrGPKWEuWXRj6+z/+8U+OZPsynh1ExjBbfUMscT rmPoVhP2+iuzhB43shYJUK/fMxiueXaM7ZVc1a8XJE6SgDeTm7dPjQtFDy+ybT5r08ED91zl4Oi4 5kuuZyxUfH8Dj/CM6DiS4udiDVhUaeG280qlljZbe5MKFZinZUpyMljU+5tZGJzMbUUVBwBVhc0E eNEf73attOeTqmC9wZIIXXXuTwDc2d8KGv5o2pajZj9kMHaH6urgIVG0bp0fZ9vJ1NWDvyX53ytn gGCMD10kHrUzHfYZhY0tyHdXhb0YcLspoZ893dnuKXKUFftvujiK8CYeLJzEE5MLQ4+s5INhJS36 eZxdXOmuAgjtVRrS8d668fJDucaoFET6JMOZLajm8vg4hILXxsl4yKQnPbq9bgZu32x0kH51QKeF wng= =UG/j -----END PGP SIGNATURE----- --------------85ngTJZ6nDGGF0DAemINvGcg--
