Can you please double check that commit bdd79ee31bf8 is good and commit 40556a4c485d is bad. Also check that commit fdb82f0a3d19 is good. In that case we have the unlikely event that the (automated) git merge is not correct or patches on each side of the merge semantically interact badly. I guess the next thing to try is just Linus' tree (commit 5170a3b24a91) merged with the nfsd tree (commit 2fc193cf924e). You should also post your information about the crash you are diagnosing as others may have seen it as well - or know what may cause it. --=20 Cheers, Stephen Rothwell sfr@canb.auug.org.au --Sig_/k/EspPWTzP/8YpgndVhqCKN Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJTtsQIAAoJEMDTa8Ir7ZwVT8YQAJHzYeZf6IF73wGmY34jtcBg NV9sjuZkz5lsbxn16Jf/QKP+55REwBV49S1rZ3xgd61Xkvp1IDnIEGStV/cvCHDp B3Y0fMRcJdkr+rnEncyhQMCVET1CclYc27I9/hdVhP2WYCxITF5C+NgRmUC0kI3I NLjZktEOV2BXqRidStejPgyVWUfaYKnKjWKiprjmJGixPmHQLepU+38ni3zJnqjD Gr7eD9jQbojPhz5rx0dK69uPF3pRV8W48y9qokq+L96T4rRA1RX0dEoTRhHnN8Ya Z9uuPjOjIqXNeL3716s9Wm2sMmjfuAR3pXU+D+kIMcAhKCLEat7JCfchCVdtUE7B nE4xVo3aGV/StIJSAsDGg6AO4Bv6G+QYTogXCkagu6JSfyCusYFcDyu37nykMKOo 8uLU9fqXeC2dcB4WHT/Jl8KkOhCJvwQfKLBO24+u3G3U63Hh0tmcFpsrUo+CUwhd xjN5htGMMHL+45wrt96x5tXS7U3yNh91uhJkVnjPlYOiXq0u8XOIr8ETOKXAmYPq rY7S+bASeZWOtQwNrKOeEvFO0lo5Me5IpLxlQ3bPN2RfmzjM9RWUzYj4uv1bVBIQ 98O634e2GkZqjWXHylmGRWSkUaHbBSWoE9UqWvYdGe03qhv4Z36ZWOAoDNuhfaoN tUay6k8nubBoBQ5peEe8 =B9sz -----END PGP SIGNATURE----- --Sig_/k/EspPWTzP/8YpgndVhqCKN-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
