Creation time

[Hubert Kario]

=46rom what I could find, btrfs supports only the trinity of UNIX time =
stamps:=20
atime, ctime and mtime.

Is there any plan to support crtime (creation time)?

Side note: ZFS already supports it, ext4 and cifs (samba) are waiting f=
or APIs=20
and userland support, so it could be a good time to coordinate efforts =
and=20
solidify the interface.

There is room in btrfs for a fourth time called "otime", but it is not
currently used or even initialized. Once there are APIs, it should be
possible to add crtime support with a slight format upgrade.
