Every time we change struct stat, we need to create legacy syscalls or libc code so the fewer changes the better. > I don't know at what level you mean to move to 64-bit inode > numbers, but if (for instance) you meant a 64-bit value for st_ino, Since an inode number needs to fit into an ino_t, I would expect that ino_t and hence st_ino would both become 64-bit. > then I'd also like to see a 64-bit value for st_dev at the same time. I can see the reason for having more than 2^32 inodes in a filesystem. It's not as obvious why you would need a 64-bit dev_t. You're never going to have more than 2^32 devices attached to a system and I would suggest that it's unlikely that you would have more than 255 active drivers on one system. What other struct stat changes are up for discussion? --=20 Peter Jeremy --k1lZvvs/B4yU6o8G Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGYI10/opHv/APuIcRAr7NAKCowqYE1R1LmDLhD1tbVFGHWgt2mQCgojdA BD4Rv14/AcS/AvrrsKgs8OY= =5qbZ -----END PGP SIGNATURE----- --k1lZvvs/B4yU6o8G--
