Specifically, it's not the overhead, so much as it's the implied side effects. Consider this going forward: someone adds a new VFSOP to the list of allowable VFSOPs, and the vfs_init() doesn't have any specific code for it. This could happen with a new VFS implementation that gets loaded as a module. While the current code can't really handle this well, the changes move us further away from ever being able to handle something like this. 8-(. -- Terry
