Subject: XFS noikeep remount in 2.6.27-rc1-next-20080730

I mount a bunch of XFS filesystems with "noikeep,attr2,noatime", and a
couple also with "ro".

Sometimes I want to remount one of the "ro" ones "rw", to make changes.
This doesn't work anymore in 2.6.27-rc1-next-20080730. The last kernel I
tried which it worked in was 2.6.26 release.

luna ~ # mount -o remount,rw /usr
mount: /usr not mounted already, or bad option

luna ~ # dmesg | tail -n 1
[18702.291344] XFS: mount option "noikeep" not supported for remount

Is this intended behaviour?
