Enabling DEBUG_STRICT_USER_COPY_CHECKS causes the following
warning:
In function 'copy_from_user',
inlined from 'rfcomm_sock_setsockopt' at
net/bluetooth/rfcomm/sock.c:705:
arch/x86/include/asm/uaccess_64.h:65:
warning: call to 'copy_from_user_overflow' declared with
attribute warning: copy_from_user() buffer size is not provably
correct
presumably due to buf_size being signed causing GCC to fail to
see that buf_size can't become negative.
