| |
Hi,
I am new to Linux kernel and now working on a project, which tries to modifies the kernel a little bit and get some blocking information about system calls. That is, if a system call gets blocked (put into sleep), I want to know the "reason for sleep" and the "file name & line number which causes the blocking".
I know that there are data structs in FreeBSD holding these information, but I don't know if linux has the same facility (functions / data structs). Hope someone can give me a hint.
Also, I wonder if ru_majflt in struct rusage (linux/resource.c) is already implemented.
Thanks! Yi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
