Could this be a solution for modules that intercept system calls from "normal" processes ?
Assuming fork() and friends are intercepted, could a new personality be set which would use-count the module, preventing the unload-whilst-processes-sleeping problem ?
I'm unsure whether this lcall7 thing would work at all... would the normal process still go through ENTRY(system_call) ?
this would be a much nicer solution than use-counting each system call individually, implying atomic_inc/atomic_dec each time, or making the module unloadable and providing ioctl()s instead of module parameters.
Is this possible ?
thanks john
