[PATCH 3/4] exec: simplify the compat syscall handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The only differenence betweeen the compat exec* syscalls and their
native versions is the compat_ptr sign extension, and the fact that
the pointer arithmetics for the two dimensional arrays needs to use
the compat pointer size.  Instead of the compat wrappers and the
struct user_arg_ptr machinery just use in_compat_syscall() to do the
right thing for the compat case deep inside get_user_arg_ptr().
