Can't remove 'noatime' on mounted filesystem on CURRENT

[Karol Kwiatkowski]

Hello,

I originally posted about it @questions [1] but now I think there's a
bug in CURRENT somewhere. System is yesterday's FreeBSD 7.0-CURRENT i386

It seems to be impossible to remove 'noatime' property on mounted
filesystem (via -u option):

# mount | grep ad0s3e
/dev/ad0s3e on /data (ufs, local, noexec, nosuid, soft-updates)
# mount -u -o noatime /data
# mount | grep ad0s3e
/dev/ad0s3e on /data (ufs, local, noatime, soft-updates)
# mount -u -o atime /data
# mount | grep ad0s3e
/dev/ad0s3e on /data (ufs, local, noatime, soft-updates)

This works on 6.2-RELEASE.

Btw, setting 'noatime' removes 'noexec' and 'nosuid' in above example.
Is this expected behaviour? Can't decide after reading mount(8).

Thanks in advance,

Karol
