Actually, I've been looking for a way to lock down chunks of user memory from within the driver I'm writing without the permission check in mlock. Is there a clean, exported interface to this? Or perhaps it would be enough to set some bit in the page tables (other than the dreaded reserved bit -- that would probably trash the user program anyway). The kernel code to do this did not seem to make much sense, but I'm no expert in the memory subsystem. Thanks!
