However, it was overeager and also refused # to truncate arguments as well, which broke userspace, and it was # reverted. This attempts the protection again, but allows arguments to # remain truncated. In an effort to improve readability, helper functions # and comments have been added. # # Co-developed-by: Linus Torvalds # Signed-off-by: Kees Cook # Cc: Andrew Morton # Cc: Oleg Nesterov # Cc:
