Remount does not work, does it ok?

Hi!

Command sequence does not work:
mkdir -p /tmp/1234567
mount -o rw -o nomtime -o pgread -o size=10m -o mode=0777 -o noexec -o nosuid -o inodes=128k -t tmpfs tmpfs /tmp/1234567
mount -u -o ro /tmp/1234567
mount: tmpfs: mount option <pgread> is unknown: Operation not supported
...
mount: tmpfs: mount option <mode> is unknown: Operation not supported
...
mount: tmpfs: mount option <inodes> is unknown: Operation not supported
...

Only
mount -o rw -o nomtime -o size=10m -o noexec -o nosuid -t tmpfs tmpfs /tmp/1234567
wokrs.


Can it be fixed?
