After upgrading to 2.4.19-pre7-ac2, I can't get CONFIG_RAMFS

Gee, I hope CONFIG_RAMFS isn't going away. I need it to do loopback mounts of cramfs on an embedded system that uses tmpfs as its main filesystem. (tmpfs doesn't support loopback mounts.)

The release notes say that ramfs needs a bit of work, so if you found ramfs was broken, maybe that's why.

o       Removepage hooks as per old -ac                 (Christoph Rohland)
        | This lets shmfs/ramfs keep accounting straight
        | ramfs needs someone to drop in the other old -ac bits stil

I beleive it's there by default after -pre7, but somehow it doesn't work

CONFIG_RAMFS is probably going away, but that doesn't mean ramfs is going away. At least in Linux 2.5 ramfs will end up being required core code.

According to what I was told by a guy at #KernelNewbies, CONFIG_RAMFS isn't there in (menu|x)?config after -pre7, but in by default. problem is
- it doesn't work
