That depends on your code, if it is still in use, yes, it will not be freed, you have control over that as this is your userspace code. There is nothing in the kernel you can do about this, sorry, please just fix up your application. good luck! greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
