What is the issue with the xstat, new stat format stuff? Basically I have the feeling that this is in discussion for at least 5 years or so and I always wondered where it is stuck. I am not aware of any discussions of it recently, but I may have overseen those. Ext4, I think, already supports birth time, but cannot expose it either. And even the stat command already seems to have some support for it, except that it doesn´t work yet (this is on BTRFS, but on Ext4 its the same). merkaba:~> LANG=C stat /bin/ls File: '/bin/ls' Size: 118280 Blocks: 232 IO Block: 4096 regular file Device: 14h/20d Inode: 3574391 Links: 1 Access: (0755/-rwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2014-10-31 11:29:37.000000000 +0100 Modify: 2014-10-30 03:43:06.000000000 +0100 Change: 2014-10-31 11:29:41.440773090 +0100 Birth: - Any pointers? -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
