Hi,
I've had a kernel compile problem recently, WITNESS_WARN implicitly
declared and WARN_GIANTOK and WARN_SLEEPOK undefined.
I don't have the WITNESS option enabled for my kernel.
I've tracked this down to lines 311ff in sys/sys/mbuf.h, #define
MBUF_CHECKSLEEP(how)...
Changing these lines to:
#ifdef WITNESS
#define MBUF_CHECKSLEEP(how) do { \
if (how == M_WAITOK) \
WITNESS_WARN(WARN_GIANTOK | WARN_SLEEPOK, NULL, \
"Sleeping in \"%s\"", __func__); \
} while(0)
#else
#define MBUF_CHECKSLEEP(how)
#endif
fixed my problem.
