hi, i'm trying to run oprofile on 2.6 kernel running on mips board.But when oprofile makes a system call to "sys_lookup_dcookie" function to find the file path of a particular sample,the function "copy_to_user" fails and no byte of path is copied to user sapce. I checked all combinations for source buffer like using array instead of pointer but no success. Please suggest me what might be the cause of failure. regards, kernelcoder
