For the record, this is not a problem. There is the global
diskfs_fsys_lock that prevents that.
What happened to the corresponding fatfs change though? Isofs is
read-only, and tmpfs' diskfs_reload_global_state is a nop too. So
modulo the missing fatfs fix this patch looks good to me.
Samuel, Thomas, is this still a smallish change that we can
just merge, or do we need to do the paperwork now?
