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