In short, because of devfs. mknod is not needed, and shouldn't be used, as nodes created with it won't work anyways. > Next I tried to use objcache instead of plain kmalloc() to allocate > tmpfs nodes and direntries.

It indeed seems as if the caller didn't enter the critical section. > 2 diffs to Alex Hornung's tree are attached: first uses kmalloc(), > second uses objcache. > When I've some time, I'll add your patches to the repo, but in general, I would recommend you contact Simon "corecode" Schubert or Matt Dillon so you can get a leaf account, where you can keep your own repository.
