hi all, a small Q. :) if i dereference a user-space pointer from inside my driver (kernel code) without the customary checks of of copy_[to/from]_user, then if the page i'm accessing is not available, it would cause a page fault. the kernel then "oops". why is this so? can't we gracefully recover from here ....we still have the user process's context with us. The page fault handler would get the page in...and I can go about doing my business. my code would sleep, but then that's OK with me. thanks as usual, -mandeep -- Kernelnewbies: Help each other learn about the Linux kernel.
