Ah, forgotten about that. Unfortunately the latency tracer patch doesn't compile either: CC kernel/latency_trace.o kernel/latency_trace.c:28:21: error: asm/rtc.h: No such file or directory kernel/latency_trace.c:63:3: error: #error Implement cycles_to_usecs. kernel/latency_trace.c: In function ‘____trace’: kernel/latency_trace.c:658: error: implicit declaration of function ‘irqs_disabled_flags’ make[1]: *** [kernel/latency_trace.o] Error 1 Miklos - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
