[PATCH] btrfs-progs: setting of time to the root directory

[Tsutomu Itoh]

This patch adds the setting of time to the root directory to the
mkfs.btrfs command.
As a result, the time of the mount point not correctly displayed
comes to be displayed correctly. 

[before]
 # mkfs.btrfs /dev/sdd10
 # mount /dev/sdd10 /test1
 # ls -ld /test1
 dr-xr-xr-x 1 root root 0 Jan  1  1970 /test1

[after]
 # date
 Tue Nov 16 18:06:05 JST 2010
 # mkfs.btrfs /dev/sdd10
 # mount /dev/sdd10 /test1
 # ls -ld /test1
 dr-xr-xr-x 1 root root 0 Nov 16 18:06 /test1

Thanks,
Tsutomu
