Subject[PATCH 4/6] kmod: return -EBUSY if modprobe limit is reached
Date
Running out of our modprobe limit is not a memory limit but
a system specific established limitation set to avoid a possible
recursive issue with modprobe. This gives userspace a better idea
of what happened if we can't load a module, it could use this to
wait and try again.
