The type pthread_t is not portable because it is freely defined.
On Linux, it is an unsigned long int which can be printed with %l.
The debug printing of the thread id is restricted to Linux only.

Forgot to add:
On FreeBSD, it is a pointer.
That's why there was this error:
drivers/net/failsafe/failsafe_private.h:377:53: error:
format specifies type 'unsigned long' but the argument has
type 'pthread_t' (aka 'struct pthread *')

On Linux, it is an unsigned long int which can be printed with %l.
On FreeBSD, it is a pointer which can be printed with %p.
