Hi, I have small doubt regarding copy_to_user/copy_from_user macros:
-Can these macros be used in interrupt context.. what if page belong to user address is not in memory (not loaded/swapped out)? -If we use copy_to_user in interrupt context, then how can this be assure that data is copied into correct process buffer? As at a time of interrupt it can't be guaranteed that intended user process is the current process running. These may be silly question but create some confusion for me.... Thanks, Chetan Nanda
