All this should go with such a patch IMHO (at lea= st > pointers to relevant discussion). The information isn't relevant since the patch didn't change them, and if you were interested in changing the values then simple google search would return a plethora of research on RTT estimation. > Must go over it with a fine comb to make sure no unrelated 2 or 3 got > replaced... out of my league, sorry. There are stray constants all over the place, which is something that even freshman computer science students are taught to avoid. This patch represents a minor improvement to that situation. -Wes --ZGiS0Q5IWpPtfppv Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFAiYAyzBuYqbnj3IwRAjhPAKCBRdDgGsALp9DTh5qFK+41cTEb6QCfUENV XM5O6g2f/gEt/3X2IoG5xAw= =Dfxq -----END PGP SIGNATURE----- --ZGiS0Q5IWpPtfppv-- - 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/
