Yes. Maybe crashme as well; has anyone run it on
recent kernels?

Speaking of crashme, is there a filesystem version of it?
It would go something like this:

for (;;)
p = random filesystem operation (read,write,seek,mkdir,etc)
perform p on the real victim filesystem
perform p on an internal model of VFS semantics
compare; if different, complain

The file contents could be deterministically-random
junk so that the internal model needs only metadata state.

Run several concurrently to test a local filesystem,
or perhaps bang on an NFS server from many directions.
