I want to be able to turn the swap on and off from within a kernel module I've written. I can't call the functions sys_swapon/sys_swapoff directly because they both take a char* arg which is the swapfile name (i.e. "/dev/hda5"), and since they do a user_path_walk() on that string to get the inode info, the char* pointer must be in userspace not kernel space. so (1) is there any way for me to do the equivalent of kmalloc() in my kernel module, but have it return a user-space pointer? so i could then fill that in with the filename and call the functions directly? or, (2) another way to do what i'm trying to do? thanks anthony __________________________________ Do you Yahoo!?
