Bug in caching of mount options

Hello All,
I have found a bug in the kernel, which I believe is related to the
caching of mount options. It shows up under both 2.0.31-pre10 and
2.1.57.

If I mount a filesystem with the noexec option, then I (of cousre)
cant run any binaries on it. If I remount it with:

mount -o remount,exec /mnt/zip

I can still not run binaries which I tried to run before the remount,
but I CAN run new binaries which I copy into the file system.

I can be more detailed if some one wants me to, but this is pretty
easy to reproduce.

Thanks,

Jim
