Don't waste time checking it. If # someone tries to access it, it will SIGFAULT the same way as for # address 1, so no need to make it special. # # The special case is when not doing a write, in that case we want # to drop the entire function. This is now handled by 'dir' param # and not by the nulity of 'to' anymore. # # Also make beginning of prevent_user_access() similar # to beginning of allow_user_access(), and tell the compiler # that writing in kernel space or with a 0 length is unlikely # # Signed-off-by: Christophe Leroy # Signed-off-by: Michael Ellerman # Link:
