--- Comment #9 from Pauli <[email protected]> 2009-09-14 11:17:06 PST --- Problem is that user space pointers are invalid in kernel space so we have to copy and convert the data before entering kernel memory space. That is required for all pointers passed to drm. http://www.cs.helsinki.fi/linux/linux-kernel/2002-06/1512.html has explanation about possible fails in copy. Which means we need compat ioctl layer to handle the copy. Another option probably would be converting the user-space pointer to kernel address space but I could find how to do that. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
