This patch adds a new member to the 'struct btrfs_inode' structure to hold
the file creation time.

Well, how do users use this file creation time? There's no syscall and there's
no ioctl that exports this information. That xstat syscall hasn't been accepted,
so you can revise and repost the patch when you see it happens.

In my opinion we should still include this patch. Currently, otime is never even
initialized, having undefined values. If it ever gets possible to
access otime, we
would at least have some inodes with valid otime fields.

I'll second that, even if by now the fields get correctly initialized.
Why should we zero the fields instead of setting them to the correct
values?
